Finally I was able to delete these tickets using the generic agent. But since then our otrs does not send any email. The communication logs shows again more than 1000 open communications and the number is constantly growing. Why is otrs queuing these messages without sending it? Where can I start searching for the reason?

Depending on your mail configuration, sending takes time. It needs a working DNS and a good MTA. On specific (wrong!) Mail configuration OTRS tries to send mails to non-existend users. Maybe you have this situation. Check your communication log and try to use the otrs.Console.pl command to check the mail sending queue and/or delete it. Check your local syslog and mail log, too. regards Florian
