- Plesk Onyx for Linux
- After upgrading to Plesk Onyx, there are email messages from email@example.com :
This is the mail system at host example.com.
I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to postmaster.
If you do so, please include this problem report. You can delete your own text from the attached returned message.
- Upon sending an email to
psaadm(system user) the following error is shown:
mail from: firstname.lastname@example.org
250 2.1.0 Ok
rcpt to: email@example.com
550 5.1.1 <firstname.lastname@example.org>: Recipient address rejected: User unknown in virtual alias table
The following error appears in
postfix/error: 42B11620B2C: to=<email@example.com>, orig_to=<psaadm>, relay=none, delay=0.02, delays=0.01/0/0/0, dsn=5.0.0, status=bounced (User unknown in virtual alias table)
firstname.lastname@example.org absent in the virtual alias table:
# postmap -s /var/spool/postfix/plesk/virtual | grep email@example.com
This is an expected behavior on Plesk Onyx servers that have been upgraded from Plesk 12.5 without preliminary removing Customer Business Manager (CBM).
The issue is caused by the CBM cron task
left after an upgrade.
