[BlueOnyx:02888] Question regarding aliases / usernames (i.e. sales, info, marketing)

[Christoph Schneeberger]

Hello,

I see the same symptoms as explained in

http://www.blueonyx.it/pipermail/blueonyx/2009-May/001169.html

However the solution seems different for me as the DNS is fine.

The situation is that I imported a site from a Bluequartz with a user
named "sales". If I comment the sales alias in the alias file and run
newaliases the mails get delivered to the correct user (at least
sendmail -bv sales at customer.com implies then so in contrast to having
the sales alias the mails are delivered to admin which imho is correct
behaviour as far as it concerns sendmail).

I then went ahead, opened an account marketing in a different domain
exposing no problems yet, this worked fine but mails to
marketing at different-domain.com now go to admin too. I first thought its
just a problem of the import, ignoring the fact that sales, marketing,
info etc. are forbidden as usernames but at least marketing worked as
username, but not as mailbox/email-address.

Shouldn't be usernames that exist in the alias file be forbidden to
create new accounts with (i.e. info, root, marketing, postmaster
whatever)? I'd never name an account info or sales btw, but every
customer tends to do so.

On the other hand, I can't imagine that nobody else has come across this
problem yet and that my customers are the only ones using info, sales
etc. as login names. So I am pretty sure I am doing something wrong, but
I can't find at which point.

Thanks in advance for any pointers/tips/hints!

Cheers,
Christoph Schneeberger
