we've recently upgraded our server from redhat 9 to fedora core 1. now we've the problem, that qmail doesn't deliver mails to our virtual domains anylonger. fetching mails would work - as i can see in the logs the correct maildir will be read for the specified user (pop3).
it's still possible to send mails to users of the main domain registered for the server, but not to users using a virtual domain hosted on the server. the sender will get back the e-mail with the well known error-message (tried to deliver for 4hours etc....). the domains are set up correctly (including mx-records) - everything worked correct as long as we had redhat 9 installed.
----- Transcript of session follows -----
<firstname.lastname@example.org>... Deferred: Connection timed out with xxxxx.xx.
Warning: message still undelivered after 4 hours
Will keep trying until message is 5 days old
maybe the upgrade messed up the qmail-configuration files for the virtual domains, but i can't find anything what could be wrong with them. does someone have a hint where to look?
