Recipient address rejected: User unknown in virtual mailbox table.

Issue #637 closed
Former user created an issue

Hey Team,

On the beginning just mention that this is awesome project but faced some issue when trying send out email from my existing server that is working for some time (planning to migrate to your env.) from various mail clients (mac mail, thunderbird, etc) Can you help me with this error when trying on sending email to first acccount that I`ve had created as admin but its configured with MX corectly for sure:) dns is configured like this: DNS @ -> xxx.pl MX @ with prio 1 -> aaa.xxx.pl

An error occurred while sending mail. The mail server responded:
5.1.1 xxx@xxx.pl: Recipient address rejected: User unknown in virtual mailbox table. Please check the message recipient "xxx@xxx.pl" and try again.

but when trying sending mails to xxx@aaa.xxx.pl all is ok, also when i will send emails from myself to myself like xxx@xxx.pl -> xxx@xxx.pl its working as well...

nothing special in the logs in regard of above error:(

    Which domain did you configure poste.io with? aaa.xxx.pl or xxx.pl? Have you added the other one (xxx.pl or aaa.xxx.pl) as an alias domain in poste.io?

    From a DNS perspective you need an MX record for both aaa.xxx.pl and xxx.pl that points to the correct fqdn host.

    This message "User unknown in virtual mailbox table." is not from poste. Please paste here whole log
