At 1:30 p.m. MST I went to look at a ticket I was working on and found that it had over 200 "Customer Reply (email-external)" entries showing in the thread view. A new reply would be added to the ticket every single minute (this is how often my mail cron runs). Each reply would be the exact same text as the previous ones. The system log (viewed from within OTRS) is normally filled with entries, but now had only one single entry about a "max packet size" error. I checked the physical inbox of the address that receives ticket requests and found that the offending message was sent to the system around 8:50 a.m MST and it was still sitting there. The message had an attachment of approx 1.4 MB. All other tickets sent to the system after that time had not been retrieved and were still in the inbox waiting to be collected by OTRS. I stopped the loop by manually deleting the offending message from the inbox. The rest of the messages were then promptly collected and properly entered into OTRS. I can see that OTRS was retrieving the message and appending the reply to the ticket, but OTRS was not deleting the message after retrieval, but does anyone know why this might have happened? Is it because OTRS could not retrieve the attachment as well? What I can do to prevent it in the future? Thanks, Tyler Hepworth
