[SOLVED] "Impossible to send message" error

Post by kongyong92 »

Dear all,

OTRS was working fine for me until today when users reported an error when sending emails out from the application.

Ran some tests and it seems to happen when the attached file exceeds a specific size (no exact number).

I ran 2 tests:
1. .pdf attachment with size 30.6 KB - the mail was sent out successfully.
2. .pdf attachment with size 963.4 KB - the error message below was displayed.

I have also checked the system logs but could not find any relevance to the issue and the quick simple tests that I ran above.

Any advice is appreciated!

Hi,

is the system up to date? all perl packages up to date?
Mail sending issues often are because of old software.

Hi wurzel,

Thanks for the reply.

Will have to check with the server admins but I doubt it is updated to the latest version.

Is there anywhere else that I can check in the meantime?

Was just wondering how this error could have been introduced all of a sudden.

Hi,

depending on your mail setting it also can be your relay host. Maybe it is/was updated and now these errors appear.
If you check the forum (or google) for similar errors it points to mail (exchange Server) issues, old versions, old perl packages...

Just check that it is up to date first, then read the logs of your involved mailserver(s) and we will see if something can be fixed.
For now I do not see a solution.

Hi Flo,

Thanks for your advice.

I re-configured the SMTP settings and it worked thereafter.

Core::Sendmail -> SendmailModule::Host
