Sendmail: No such user here

[Tommahawk]

ISPConfig is writing

@domain.com error:nouser

in the sendmail virtualusertable file

People are complaining to me that sending email to me they get No such user here error bounce and also I cannot send email causing squirrialmail to say when sending email.

Requested action not taken: mailbox name not allowed
Server replied: 553 5.3.0 <agpublic@5s7.com>... No such user here

what to do?

thanks in advance.

This behaviour is fine as itgives a nouser error in case that a mailbox does not exist.

If you want to receive email for a email address, you must create this email address or a alias for the amial address or you will have to enable catchall for onr mailbox in this domain.
