This sounds like one of the very rare cases where the obscure http://www.postfix.org/postconf.5.html#dont_remove option might be helpful. something like # main.cf dont_remove = 1 hash_queue_names = deferred, defer, saved If you expect to have more than a few hundred thousand files, maybe also: hash_queue_depth = 2 Caution: this will fill up your hard drive. Caution: this is a debugging tool with limited warranty. The advantage is that if you can identify a corrupted mail, you'll be able to directly compare the before-filter and after-filter queue files, and all envelope information is saved for (fairly) easy resubmission. -- Noel Jones
