Dagent and Gateway Crashed after receiving email from Outlook using RTF
-
Hi umgfoin,
The error we got is more on libkcinetmapi I think, your log seems to be more on libmapi, but I’m not sure.
Hi lherrmann,
Thanks for your time trying to reproduce the issue.
Re. RTF part, how about this part on the eml, would that be the part you’re after?
I setup IMAP on Outlook and enabled “Send using Outlook Rich Text format” under Options -> Mail. Then send myself a test email by selecting “Rich Text” as format, then formatting my text on the body (i.e. made it bold, etc). That’s when I get the error as per my original message.
-
Hi @compsos-shiena ,
yes that is the part we have also seen in your eml. it actually does not contain rtf, but is already converted from rtf to html. But unfortunately neither with your eml nor when hooking up Outlook via imap and setting the format to rtf we could observe a crash of the dagent.
-
Hi Felix,
The eml file was from the Sent folder, and not from the Inbox as it would not deliver to the Inbox. due to the crash. Would that be ok as an eml sample?
-
Hi @compsos-shiena ,
if you can reproduce the crash with the eml from the sent items we would of course love to have a look at this mail. If you cannot get the dagent to dump the raw message then an alternative approach could be to dump the message directly from the postfix queue. Step 2 in https://www.wirehive.com/5-top-tips-reviewing-postfix-mail-queue/ explains how.

Hi Felix,
I sent another test email from Outlook 2016 with Rich Text enabled and formatting was enabled on text. It was then stuck in queue.
I then followed step 2 from your link and saved the file, it can be viewed here https://www.dropbox.com/s/krkysnet4nv0v19/test-dagentcrash-251020171018.txt?dl=0Postfix on NethServer maillog when I tried to send the test email to myself was:

Ah, that already looks a lot more like an rtf body part. I’ll see if I can have someone test this in the next few days.

Yes, I should have pointed that out earlier. the dagent and the gateway are not directly connected. the dagent is used to deliver mails from the mta to kopano-server, while the gateway is utilised if you open stores via pop3/imap.

I tested this again, but no error messages came up in the agent.log file. Just one warning message (which can be ignored):
Mon Oct 30 10:26:54 2017: [26413] [warning] TNEF attachment saving failed: 0x80004002
I tested this with 8.4.90

Hello lherrmann and fbartels,
Do you think it’s the libraries we have installed like libkcutil, libpthread, libstdc++, libkcinetmapi causing our issue?
I attached the result of dpkg-query from our server https://www.dropbox.com/s/3kda0edsmibdsn0/dpkg-query.txt?dl=0
Thanks -
Hi @compsos-shiena ,
you are running quite an old version of Kopano Core. You could try if upgrading solves the issue for you.

Hi Felix,
The boss is currently away so I’m not doing an update as yet, I will let you know once I’ve done the update and hopefully if it fixed that issue.
Thank you all for your help.
