POP3: Can't process mail, email no 1 is empty!

[hugoegon123]

Hi All!

When fetching emails with attatchment from Exchange Server 2010 (POP3), OTRS won't create a new ticket and email is not deleted from Exchange mailbox.
This is not a general problem. Some attachments work:
If I attach file internet7.pdf (Outlook message size 97KB) OTRS is working fine but if I attach file internet6.pdf (Outlook message size 98KB) no ticket will be created and syslog shows:

Wed Oct 22 13:50:08 2014 info OTRS-otrs.PostMasterMailbox.pl-84 POP3: Fetched 1 email(s) from servicedesk/192.168.x.x.
Wed Oct 22 13:50:08 2014 error OTRS-otrs.PostMasterMailbox.pl-84 POP3: Can't process mail, email no 1 is empty!
Wed Oct 22 13:50:01 2014 notice OTRS-otrs.Scheduler-84 Scheduler Daemon status request! PID 1683

Maybe message size is the problem?

I already checked my.cnf and also PostMasterMaxEmailSize.

Our environment:
OTRS Server Suse 13.1
OTRS with KIX 3.3.8
Exchange Server 2010
POP3 Mailbox



Thanks in Adavance

It means multiple simultaneous fetches are occurring. Usually this means otrs and root are both doing it. If not, it means a dev or backup box is competing with production.

Hi crythias,

thank you very much for answering!

How can I find out which other process or thing is also fetching/accessing these emails?
I am wondering about every time if I use my test file internet7.pdf it works and every time if I attach internet6.pdf it doesn't work. This is no random problem. Every time same behaviour.

I can't easily tell you if another computer is trying to fetch, but you may look at services and schedules depending on operating system of OTRS.
