Concept configuration of Postfix with Smarthosts

[hispeed]

It could be that this is not the whole configuration. I really don’t get it. One of the reason I want to go away from Synology because I really don’t know how that works at the moment and I hope I understand it more if I do it on a own system.

At the moment my config I have on pastebin: https://pastebin.com/rzmybzd2
Since I have changed the postfix config I recieve that error:
Something is now wrong: fetchmail: SMTP error: 451 4.3.0 XXXX@XXXXX.ch: Temporary lookup failure -> reading message webXXXX@webXXXXX.login-12.hoststar.ch:1 of 1 (5926 header octets) not flushed |

@hispeed said in Concept configuration of Postfix with Smarthosts:

Since I have changed the postfix config I recieve that error:

so you combined your postfix configuration with the above from synology and now get these errors? Debugging postfix problems is always easier with the full error message from the mail.log and the main.cf (or the output of postfonf -n )

[hispeed]

Yes that’s right I combined that but I’m not sure if this is the actual config from the Synology which is running. I have the Docker setup from Zarafa4H. Do you know where the config is which is actually running for the Docker setup?

Ok I found the Synology Zarafa4h Docker main.config. Now when I send an e-mail to the adress I can fetch it via Fetchmail and it’s getting flushed. But I don’t recieve it in Kopano ^^. Config should be fine I have corrected it and I don’t recieve any errors right now.
This is the mail.log I see now after recieving with fetchmail:

Why is the last line:

[Gerald]

The mail is removed because it was delivered to mail.XXXX.ch[213.239.XX.XXX]. If this is not your Kopano server, something is wrong here. Perhaps postfix does not think it is responsible for this domain. Also, why is postfix involved here? If you use fetchmail to get mail and send that to kopano-dagent, postfix should not be involved ?!?

[hispeed]

I really don’t know why postfix is now involved for recieving mails. Maybe this is a question for Felix?

I have now the configuration in Fetchmail from Gerald but unfortunately i recieve this:

My questions do I need perl for Fetchmail? Something is probably wrong in the config but which config?
I don’t get more output from Fetchmail.

@hispeed Hej hispeed! Maybe this is something for you?

I created a distribution for ARMv7 (RaspberryPi, Odroid) serving all your wishes. Packages for x64 are going to be build after testing.

It brings all configuration files and a customized Postfixadmin (managing Kopano and Postfix simultaneously) you can create a standalone mailserver or one which is sending with smarthost (User- or Domainwide) at the same time. Fetchmail is working, too.

The installscripts create the ready and running server. All together your done in about 15 minutes.

Thanks for your post martimcfly. Actually I have a Odroid-C1 but I use it for something different. So I will need the X64 image. But I hope I can get it running on Ubuntu but if don’t get it work I will try your image as soon as it’s available for my platform based on esxi 6.5.

My questions do I need perl for Fetchmail? Something is probably wrong in the config but which config?
I don’t get more output from Fetchmail.

If you use the way I’m using fetchmail and have suggested it above, postfix should not be involved since it will fetch the mail and directly deliver it using kopano-dagent. So it should work even if your postfix configuration is not correct (which is probably the case :-)

As fbartels has mentioned, make sure you change zarafa-dagent to kopano-dagent. My example was copy&pasted from my installation logs and it was still called zarafa at the time.

So assuming you are now using

poll pop.srv.de proto pop3 user "mylogin" pass "mypass" options ssl smtpaddress localhost forcecr mda "/usr/bin/kopano-dagent -s the-local-kopano-user-id

as your configuration, your problem is most likely with kopano-dagent since this is the MDA (mail delivery agent) and your fetchmail complains about an MDA problem. To my knowledge fetchmail does not need perl, and the error message does not in any way suggest that perl would be a problem. I suggest you first check if the executable /usr/bin/kopano-dagent specified is correct (could be in another path on other distros? I’m using ubuntu 16.04) and if this is correct you need to check the logs of kopano-dagent why it fails.

To do so, on modern systems with systemd init and current kopano configuration files you need to check the systemd log (journalctl -u kopano-dagent -f -n 20 for example). On older crappy obsolete legacy systems without systemd+journal check /var/log/kopano/ for a dagent log file. You might need to turn up the logging level if not enough can be seen in the log why it fails. This can of course be done in /etc/kopano/dagent.cfg

If you use fetchmail the way fbartels has suggested he prefers, this is of course also perfectly fine. But then your postfix server must know for which emails he is directly responsible. Your postfix log above looked like postfix sent the email on to the internet because it did not think it is responsible to locally handle it. There are many ways to configure postfix, I’m using the virtual_ directives to tell postfix for what it is responsible. But there are other ways. If you want to go this route, the options “virtual_mailbox_domains”, “virtual_mailbox_maps”, “virtual_alias_maps” and “virtual_transport” are the most impotant. You need to really learn how to configure postfix though. If you just want to fetch some mails using POP or IMAP and Postfix will alway only be used to send mail to external recipients, using fetchmail + kopano-dagent will be much easier for you.

[thctlo]

@martimcfly are these scripts anywhere on github? and GPL?
Then im not inventing the wheel again, this is a thing i want in debian also.
The source code page says 404 to me :-(

[martimcfly]

Sorry for the 404. My Gitlab (SCM) wasn’t updated for a while and I’ve made it private for security reasons. Temporaly of course.

The bash-scripts are packed in here…

/usr/share/doc/kopano/pietma
https://repository.pietma.com/nexus/service/local/repositories/archlinux/content/armv7h/pietma-kopano/kopano-core-8.6.1-1-armv7h.pkg.tar.xz

Please be aware of the fact, that these script have dependencies and asume paths which are only guaranteed with that packages on Archlinux.

But you can get a good idea how all this have to be setup to be working.

[fbartels]

When talking about easier user management and appliances I have to throw my “go to” solution Univention into the pot as well: https://www.univention.com/products/univention-app-center/app-catalog/kopano-core/

They also have a Fetchmail app so everything can be done from their web ui.

[thctlo]

@martimcfly thank you very much for these very usefull.

@fbartels, thank for the univention link, i’ll have a look at that also.

[hispeed]

Hi folks, thanks for your answer…slowly I’m getting closer to the solution.
The problem is the dagent. I can’t start it. Is there anything to do in the dagent.cfg? Everything was commented out (auskommentiert).

Maybe I can find out more…

@thctlo i’ts always comming back ;=) 2 years are over and nobody has the problem except from me and you had it? How did you fix it?

/etc/kopano/server.cfg <- I have probably some configuration issues also there.

For me it looks like that this tutorial is incomplete as always:
https://www.pc-howto.com/kopano-der-neue-stern-am-groupwarehimmel-teil-1/
https://www.pc-howto.com/kopano-der-neue-stern-am-groupwarehimmel-teil-2/

Maybe I’m just to stupid. @martimcfly I go thru your config files by tomorrow.

[Gerald]

@hispeed

If you run kopano-dagent with the parameter -l, it will bind to port 2003 and wait for connections. [-l = listen mode]

If you start kopano-dagent with a receipient as parameter it will read mail from stdin and then (with proper input which it gets from fetchmail) deliver this single mail to kopano.

If your log says “Unable to create socket, address already in use”, then you already have a kopano-dagent running in listen mode and you are trying to start another one in listen mode. kopano-dagent cannot run twice in listen mode. But you can of course have it running in listen mode and on demand call it in interactive mode from fetchmail.

An empty dagent.cfg should be fine.

[hispeed]

Hi Gerald,

Now I’m more confident with logs and dagent. It looks now fine.

I think that I have a problem in fetchmailrc:

#.fetchmailrc
set syslog;
set postmaster "email_from_root_user_i_created_in_kopano";
# set no bouncemail
set no softbounce;
# accounts
poll webXXX.login-XXX.hoststar.ch proto pop3 user webXXXX pass XXXXXXX options ssl smtpaddress localhost forcecr mda usr/sbin/kopano-dagent -s 4

This is wrong because of “-s” after kopano-dagent. Do I have to use " " in the syntax if yes, only at mda “usr/sbin/kopano-dagent -s 4”?
Number 4 is because it’s the sql table written number 4 can I use the kopano-login name as well?

When I use it with the username and quotes " " and I have to use the directory “usr/sbin/kopano-dagent -s username”
in “bin” I don’t have a kopano-dagent only in “sbin”.
I always recieve:

Ok, I had “the-local-kopano-user-id” in my example. But that did not mean that you need to dig in the MySQL Database and search for a random hidden usernumber. What is meant by this is just the Username in Kopano.
I don’t know about the new kopano-cli but in kopano-admin this is what is specified as -u and what is listed as Username in kopano-admin -l

When I use it with the username and quotes " " and I have to use the directory “usr/sbin/kopano-dagent -s username”

Why no / in front of /usr? Might work depending on where it is run from, but this looks weird and is an unnecessary reason for it to fail.

in “bin” I don’t have a kopano-dagent only in “sbin”.

Yeah, just mentioned it because this could have been different in other distros. But I’m also using Ubuntu and sbin is correct. Easy to check:

May 31 07:23:47 svgwma-kopa-02 fetchmail[3703]: reading message webXXXX@webXXX.login-XX.hoststar.ch:1 of 1 (6722 octets) (log message incomplete) <--- WHY Incomplete??? 
May 31 07:23:47 svgwma-kopa-02 fetchmail[3703]: MDA returned nonzero status 75

I have no idea. Perhaps remove the -s from the kopano-dagent parameter (this is for silent)
Instead add -v (verbose) or -vv (even more verbose)!

Also add verbose flags to fetchmail, Syntax probably the same (-v or -vv for even more verbosity).

On the other side Kopano Core Delivery Agent with Debug Mode:
The only thing I see which is not correct, is the time. Actually I don’t know why.

I think I had this once too in some log… Don’t remember exactly, but check timedatectl if your timezones are correct.

Output for me is:

This looks like the log from the zarafa-dagent in daemon mode. (Parameter -s)
Not sure if the logs from a manually started zarafa-dagent in non-daemon mode will end up here to. At least nothin in the log you quoted.

When I want to list all Kopano users I get this:

root@svgwma-kopa-02:/home/kopano# kopano-cli --list-users
Traceback (most recent call last):
  File "/usr/sbin/kopano-cli", line 3, in <module>
ImportError: No module named MAPI.Tags
root@svgwma-kopa-02:/home/kopano# kopano-cli

Something is here wrong with the DB or so…

Does kopano-admin -l work for you? The error message looks more like you have not installed a required package?

Hi,

With verbose I recieve this:

fetchmail@svgwma-kopa-02:~$ fetchmail -f fetchmail-accounts

I will check if I can update Kopano and test again…

EDIT 1:

I download via wget the newest kopano-core and then made the package and installed it.
This worked fine so far. After the installation the system user on Ubuntu 18.04 had a new Password <- why?

Now when I want to login via Webapp I recieve this error:

Unknown MAPI Error: MAPI_E_NOT_FOUND

When I make this: kopano-admin --create-store hispeed

Then I recieve:

kopano-admin: relocation error: kopano-admin: symbol _ZN2KC21GetAutoAcceptSettingsEP9IMsgStorePbS2_S2_S2_ version KC_8.6.80 not defined in file libmapi.so.1 with link time reference

It’s getting worser from day to day ;=)…

[hispeed]

Yes yes yes…

I don’t believe it I can now recieve. I updated the whole Ubuntu and restartet. Then I had to change something in the config from Kopano. Attachament stored as File (I made there a change earlier). I’m sure I can switch that to database later.
Restarting everything and now I can recieve e-mails.

Thanks so far for everyone. There are still a few questions open like: why the kopano user gets a new password after update?

Now I have to figure out how I can send E-mails… For this I’m going to use postfix.

Postfix i’m back in trouble :D! Yes something is wrong in my postfix configuration.

Gerald or someone else:

Do you have a sample of the postfix configuration?
