Well, looking at the help for "Recipient":
"This is the address you wish the alias to go to. This can be either a local user or an e-mail address.
If you wish for the mail to go to local user "rwm" then simply enter "rwm" in the box or select it from the user chooser.
If you wish for the mail to go to "rwm@linuxsecurity.com", then simply enter "rwm@linuxsecurity.com" in the box."
Postfix takes two forms in virtual:
user@maildomain.com [ localuser | remoteaddress ]
Where "localuser" is a local username, and remoteaddress is of the "user@host.com" form. I'm guessing that the Postfix parser sees your '@' in the username and assumes it's remote, and tries to deliver it via SMTP rather then just putting it /var/spool/mail/username@domain.com.
I'd say look at postfix.org and see if there is a way around this. Neither Pete nor I know of any (I just consulted with him wrt this issue).
More importantly, I'd like some evidence that using the form "username@domain.com" is an "industry standard" for local UNIX/Linux usernames. I can't exactly say that it violates the form because I cannot find any evidence notating so, but it just doesn't make any sense to me. There are other ways around this issue: Email Address Local User Choices ------------- ------------------ user@domain1.com user1 / domain1_user user@domain2.com user2 / domain2_user user@domain3.com user3 / domain3_user
The only invalid characters I could find for a username were "upper case characters" and "colons".
Cheers,
Ryan
