SMTP Error! The following recipients failed: x@x.com: Recipient address rejected: User unknown in virtual alias table

Post by alekc » Sat May 26, 2018 10:13 am

Hello,

I've just tried to change the email address in the global configuration settings in the backend and keep on getting the following error when trying to send a test mail:

SMTP Error! The following recipients failed: x@x.com: Recipient address rejected: User unknown in virtual alias table

x@x.com would be a working & tested address I put in. When reverting back to the original address on the same domain it works.

Anyone got an idea what the problem may be?

Thanks in advance for any help,
.alex

This problem is not caused by Joomla. Search for the issue 'smtp user unknown in virtual alias table' and include the name of the SMTP mail server that your site forwards emails to.
