I created a public folder and link to an internet address. I can send to that public folder internally, by typing the full FQDN email address xxxxx@yyyyy.com. But when I test from external, the email has been returned (I can see the fetchmail has downloaded from ISP pop3 and flushed) with the error:
----- The following addresses had permanent fatal errors -----
<xxxxx@yyyyy.com>
(reason: 550 <xxxxx@yyyyy.com>: Recipient address rejected: User unknown in virtual alias table)
----- Transcript of session follows -----

Can someone help me?
