- Plesk for Linux
Unable to receive emails to a particular email account with the following error message in
550 5.1.1 email@example.com: Recipient address rejected: User unknown in virtual mailbox table
virtual_alias_maps misconfiguration. Namely the recipient address is missed in the Postfix
# postmap -s /var/spool/postfix/plesk/virtual | grep firstname.lastname@example.org
Connect to the server via SSH.
Add missing alias for the affected mailbox:
# echo "email@example.com firstname.lastname@example.org" | postmap -i hash:/var/spool/postfix/plesk/virtual
if it does not help after migration, remove mail account and re-migrate subscription mail content
Note: replace email@example.com with the appropriate email account from the error message.
