Re: [otrs] OTRS : Duplicate emails gets via POP3

Hi, We found the problem and solved with workarround. So, our problem is not related with pop server or imap server.when the backup of mysql DB it's running (with gzip compress) I don't know why (we 'are still investigating) the process otrs.PostMasterMailbox.pl crash, now we stopped running this script during the backup and solved the problem. Thanks for our support. Marco -----Original Message----- From: Marco Ferreira To: User questions and discussions about OTRS.

Depends a lot on the POP server implementation, too. If the POP server is set to rate-limit incoming connections (default on recent versions of Exchange, and most of the “free” email providers these days), the client (in this case, OTRS) will see the full list of messages in the mailbox, but will be allowed to get only a certain number per connection attempt, and will not be able to connect more than once per X minutes. This confuses the OTRS POP client a lot.

The best permanent solution we’ve found is to use fetchmail to interact with the POP server, and a local SMTP server listening only on the loopback address with local aliases for the OTRS queues. Fetchmail is much smarter about dealing with obscure remote mailbox problems, and has super-helpful logging if it has problems.
