No. qmail beginners often experience problems.

Of course, the documentations tells you to set up > relay_recipient_maps, but as a beginner you might forget to do so. qmail treats all domains included in a simple text file as locals, so *only* these domains can relay. I insist on it: qmail is much more simple and easy than all of that options in sendmail or postfix. I hope this will be a true explanation of your question... > >>> release. That is not important.

No. I didn't find anything: the only real thing is that all those messages were missed forever. > The only situation where I definitely lost a mail was, when I severely > misconfigured my machine: I send the mail to a nonexisting recipient > address.

In the worst circumstances, qmail never missed a message, even though it was a very crazy mail. I can always retrieve that, deleted from queue, etc. qmail always send a *copy* of the message, and deletes it only if message has been successed in the counterpart. > The result was, that Postfix finally deleted the undeliverable mail out of > the queue.

I do use imap too (in fact, courier-imap); but I can do pop3 and imap at the same time with qmail; only the MUA configuration and preferences makes the personal choice. It's the thing I can tell you. My English level is not as good as a discussion... And I want to repeat: all customers sang aleluyas when they noticed mail service was *really working* and was much faster and reliable than before. I was really tired with qpopper and that really annoying configuration of boxes, alltogether in a single file. This is prehistoric! I installed qmail and life of customers became bright back. All my servers installed are still there!!! From 2001... till now. Working everyday; maybe only updated the imap server, or the webmail (from qmailadmin to Squirrel, for instance), but any more. The main qmail server is still working, with a deal of charge from nearly 1000 enterprises or more around the world. For qmail the only limit is hardware, not the service itself.
