If the Official Host name is not trouble.com make sure there is a host alias
of that name

Subject: [IMail Forum] SMTP 550
Dear list,
after an upgrade from 8.15 to 8.22 a virtual domain has stopped receiving
mail that are processed through the local smtp-service. Users on the
troublesome domain can receive mail sent through the webmessaging, so
local deliveries are fine, but remote senders gets an smtp bounce that
says:
----- The following addresses had permanent fatal errors -----
<[EMAIL PROTECTED]>
(reason: 550 unknown user <[EMAIL PROTECTED]>)
Telneting to the server talking to the smtp verifies users on an other
domain and aliases for the troublesome domain but says "550 unknown user"
for users. Users are located in two different external databases and
worked great until the update.
How does the smtp-service interact with the user database? Any ideas on
what might have happened are appreciated.
// Robert
