Hi, I'll try, as you guess, setting up qmail. Everything is probably working. The problem I'm facing is that I can't sent mails to local users. I set up the home mail-dir (maildirmake et al.) using mbox delivered to $HOME. Sometimes Dave wrote (taken from the archive) that 5.1.1: What that message means is that the local recipient is not a valid address. That can happen if the recipient: - is not a user NO - has the UID 0 NO - doesn't own their home directory NO - has a home directory that isn't visible to user qmailp [I'm not sure about this point, but added qmailp to the same user-group] - has a username containing uppercase characters NO - has a username longer than 32 characters NO - isn't handled by an alias or catch-all .qmail file in ~alias [If I put an tom-qmail file in alias I get an elivery 13: failure: This_message_is_looping:_it_already_has_my_Delivered-To_line._(#5.4.6)] If I remove that alias I get the following in /var/log/qmail/current snip @400000003aab87ae2bab487c status: exiting @400000003aab87b31f767b44 status: local 0/10 remote 0/20 @400000003aab8ce2342a54fc new msg 224638 @400000003aab8ce2342a9b4c info msg 224638: bytes 204 from <[EMAIL PROTECTED]> qp 16101 uid 0 @400000003aab8ce2373ef79c starting delivery 1: msg 224638 to local [EMAIL PROTECTED] @400000003aab8ce2373f45bc status: local 1/10 remote 0/20 @400000003aab8ce23ab75d4c delivery 1: failure: Sorry,_no_mailbox_here_by_that_name._(#5.1.1)/ @400000003aab8ce23afb347c status: local 0/10 remote 0/20 @400000003aab8ce23b94d884 bounce msg 224638 qp 16104 @400000003aab8ce23b97265c end msg 224638 @400000003aab8ce303d233ec new msg 224641 snip Thanks for any help Tom
