Hi, I had the same problem earlier and I first ran into new errors by modifying Config.pm with $Self->{'PostMasterPOP3MaxEmailSize'} = 1024 * 10; and not modifying SQL option max_allowed_packet. Now I have also modified /etc/my.cnf, everything is working propoerly, thanks. But I have still a related question. Is there a way to be notified if an email which size is greater than the PostMaster limit is fetched ? At this time, there is an error in the OTRS logs but it would be nice if the customer automatically received an email saying his attachement was too big. I am sure you can do this by modifying the .pl script but I am wondering if anyone has already done it.
