I had a problem with my qmail, and basically had to do a package add of qmail again, that fixed my queue and other issues.

Now all the email on the server works except for one domain

How do I re-enable the email for that domain? I get the following when sending mail to it.

<user@domain.com>:
Sorry, no mailbox here by that name. (#5.1.1)

I've done mchk -v

I've disabled the domain and re-enabled it.

I've changed spam settings.

I've checked that popuser owns the mailboxes, everything is the same as one of my other domains.

next steps I haven't tried.

remove the whole domain?

Ideas?

 

Try this
/var/qmail/bin/qmail-newu

Man qmail-newu

NAME
qmail-newu - prepare address assignments for qmail-lspawn

SYNOPSIS
qmail-newu

DESCRIPTION
qmail-newu reads the assignments in /var/qmail/users/assign
and writes them into /var/qmail/users/cdb in a binary format
suited for quick access by qmail-lspawn.

If there is a problem with users/assign, qmail-newu
complains and leaves users/cdb alone.

qmail-newu ensures that users/cdb is updated atomically, so
qmail-lspawn never has to wait for qmail-newu to finish.
However, qmail-newu makes no attempt to protect against two
simultaneous updates of users/cdb.

The binary users/cdb format is portable across machines.
