I am getting an error with the sending of external mail via Exchange server
in SBS 2003 SP1

The following address(es) were not reached:

  i***@emailadres.net on 12-11-2005 16:25
the message can not be deliverd because of a configuration error on the
server. please contact the administrator.
  <Domain.nl #5.3.0 smtp;553 5.3.0 <Administra***@domain.nl>... No such
user>

I think it has something to do with the relay restrictions of SP1 on SBS
2003, but how can I turn this of. I did install the Windows 2003 SBS pre SP1
and did not have this problem.

Thanks in advance,
Pascal

Show quoteHide quoteNot sure where relay enters into it - are you using POP/IMAP to send mail?

I am using smtp server from provider to send email.
All email is delivered directly to the provider.

Using the pop/smtp account in outlook works fine to send external email.
But using the exchange account gives the error.

Email comming in by pop3 connector SBS 2003 works fine too.

If you're using your ISP's SMTP server, not Exchange's SMTP server, to relay
mail (in your POP account in Outlook), it has nothing to do with your own
server per se as regards relay.

When you send mail from your Exchange mailbox, you aren't relaying mail -
Exchange is sending it directly out to the recipient's server, or forwarding
all outbound Internet mail to another SMTP server as a smarthost (depending
on how you set it up).

Why are you mixing/matching accounts in outlook? I would avoid this. It
doesn't give you the full functionality of Exchange, you can't use OWA for
everything while out of the office, etc - I'd desist & instead let Exchange
handle all your mail. I'd even ditch the POP connector if it were me...use a
registered internet domain name & host your own mail directly.

Note that SBS questions are best asked in
microsoft.public.windows.server.sbs - you should get a lot of help in there.

We have an old email from the provider witch is know to a lot of customers.
And we can not change the MX record for this mail address.
It did work in 8 other cases in pre sp1 installation

I will ask it overthere as well.
Tnx for the trouble.
