Plesk - Postfix - Lost Emails

[ThomasBereczky]

Dear Parallels,

We are currently sending out 5700 Emails / week as a newsletter. We moved a couple of weeks ago from a Plesk 11.09 Rackspace Server to a New Plesk 11.5.30 Server.
Since the migration we sent out 2700 emails / week instead of 5700 Emails. We checked the logs (/usr/local/psa/var/log/maillog), and there is around 2000 lost emails. Can you give us some suggestions if there are some limits set in Plesk?

Best Wishes,
Thomas Bereczky

Not enough information to assist here. Why do you think there are 2000 mails lost? What do the logs say?

There are no mail limits configurable in Plesk 11.5. We sent out about 1 milllion mails a month with no problems at all.
