Error Impossible to send Message

Post by tpsupport »

Dear community,

at the moment we get an error message when trying to reply some customers from OTRS. When attempting to send the message you will see an error saying "Impossible to send message to: xyz@abc.com, .". the message itself is added to the ticket (you can see it in the ticket view) but it is not sent to the customer. if you look into the article on the file system you will see that a plain.txt file is missing for the article. The error seems to be on a per ticket basis as this happens all the time only fore some tickets. Our workaround is to create a new email ticket, copy the message and merge it to the original ticket afterwards. If you then send the message from the original ticket, everything works again. Here is what I found in the log.

Code: Select all

[Tue Jan 15 09:27:44 2013][Error][Kernel::System::Email::SMTP::Send][163] Can't send message: 354go ahead
! Enable Net::SMTP debug for more info!
[Tue Jan 15 09:27:44 2013][Info][Kernel::System::Email::Send] Error sending message
[Tue Jan 15 09:27:44 2013][Error][Kernel::System::Ticket::Article::ArticleSend][2176] Impossible to send message to: xyz@abc.com, .
According to some websites the message "354go ahead" comes from the SMTP server and just means that the server is now waiting for input from the email client. So, I would think that OTRS is the one to blame but this happens since our Admins introduced a new firewall, so I am not sure. Every information is very much appreciated.
