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 <[email protected]>... 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.
