Hi,

I've recently switched to LMTP as I'm now using mdbox. However since switching, mails sent to the root account do not get delivered due to the following error:

May 1 18:20:17 Server1 postfix/lmtp[13019]: CAEE91F851: to=<root@test.com>, relay=mail.test.com[private/dovecot-lmtp], delay=1097, delays=1096/0.45/0.43/0.46, dsn=4.3.0, status=deferred (host mail.test.com[private/dovecot-lmtp] said: 451 4.3.0 <root@test.com> Invalid user settings. Refer to server log for more information. (in reply to RCPT TO command))

This obviously fills up my mail queue.

All other mails to all other mailboxes deliver fine.

I'm obviously missing something in my config... any ideas?

I'm using Dovecot 2.2.12 on NetBSD 5.2.2.

Many thanks,
