The virus notifications that go to my admin user are being bounced:

<admin@servername.domain.com>: unknown user: "admin"

The entire zimbra.log snip is below. admin@servername.domain.com is an alias on my admin@domain.com account. If I manually send email to admin@servername.domain.com, it gets delivered to my admin@domain.com account normally.

Does anyone have any ideas what may be up?
