SMTP Relay Solution Via Provider
Not sure if this is the best place to post this issue…but I’ll try:
In the context of kopano installations, I have read about
"SMTP Relay Solutions via Provider"
There are great posts from Andreas about that.
Before I am going to install a Kopano server for my big family, I would like to understand a few things.
So far, I see the these steps required:
- create Kopano User
- E-Mail-Alias(es), zB email@example.com or firstname.lastname@example.org, eintragen
- ‚Request mail from external server’ has to be activated -> receive mails via POP3 (e.g. from GMail-Account: email@example.com)
so far, so good…
The domain “wir.com” is hosted at myISP, where I am getting the SMTP access credentials from, before adding them to the postfix smtp_auth file.
Now some questions:
What exactly has changed after restarting the postfix module with the newly configured amtp_auth file?
Does it have any infulence on how the sender email address appears for the recipient?
I hope I could explain my questions well enough…
I am aware of the spam-topic, so a professionally hosted ISP mail server (blacklists, SPF, etc) are certainly a good choice in such a setup.
what are you planning in general?
Will the Kopano server be at your home or on a virtual machine at the internet?
As far as I understand - the MX should point to your provider and kopano server will collect mails from several other accounts?
Which post from Andreas did you mean?
I was referring to this article:
where Andreas is partly pointing out how to make use of an SMTP relay, so I asked here for more details.
Kopano will run on my own physical server.
The users (partly) already have their email addresses, which I would like to use for their Kopano accounts (actually, they do not want to change their existing email accounts), as pointed out in the exampes above.
Hi @ThomasB ,
do you have experience with Linux and postfix?
Looks like with postfix it’s possible:
If your server is at home, ensure you have at least VDSL connection and a dyndns Service.
