can't receive mail after completed server backup

[WillemK]

I do a nightly server backup to an ftp server. I have 40 domains and the total data is 35 gb.

After the backup successfully completes, one particular domain can no longer receive email. All email sent to will bounce with:

Sorry. Although I'm listed as a best-preference MX or A for that host,
it isn't in my control/locals file, so I don't treat it as local. (#5.4.6)

After a restart of qmail mail will be delivered again, but obviously this is not ideal.

Any ideas?

Thanks,

Willem

Hello,

Try to rebuild Qmail configuration files using /usr/local/psa/admin/sbin/mchk utility. Please, check the following article for the reason of such a bounce:

I have already rebuilt the qmail config using the mchk utility and i am aware of what the bounce message means.

The domain that the email bounces for IS correctly entered in the rcpthosts and the virtualdomains files.
As soon as I restart qmail everything starts working again.

Something that happens during a complete server backup confuses qmail. I read somewhere else that it might have to do with having domain alias, but other domains that have a domain alias do not have this issue, and regardless of that removing the alias is not an acceptable solution

I think it is the same problem as described here:
