as well as the Access Denied little problem that I have already posted about
I have one other BIG problem. Its come to my attention that some one is
using our exchange server to forward bulk e-mails.
I went to the IMS and under the Connections tab set the IMS property in the
Accept Connections section to 'only host using: Authentication'. I changed
all the clients in the office and everything seemed fine, no more spamming.
Until I noticed that I'd not actually revived any incoming mail from outside
the company. Using a web based mailer I tried to send my self something and
got this back ...

Please, any help? And a way of stoping this bulk remailer?

on the 'Routing' tab (not the Connections tab). That should take care of it for
you.

The current settings in the Internet Mail Service look like this.
Under the Connections tab, everything's default, I'm accepting connections
from any host.
Under the Routing tab, I'm allowing re routing of incoming SMTP but have
added some restrictions. (Hosts and clients with IP's in out domain). I
tried using only authenticated users but it seemed to stop outgoing mail
getting delivered.
I've tried quite a few things and I'm pulling my hair out here. I know its a
pain but could some one lead me though this? The forwarding of mail by the
phantom spamer is solved at the moment. But exchange is being a bit picky
about who where allowed to send mail to! It lets me send to some people and
not to others? The error I'm getting is ...

The recipient name is not recognized
The MTS-ID of the original message is: c=US;a=
;p=Multicom;l=CHARON0105171419LD1JGZLP
Any help is very much appreciated.

Have you configured mail clients to authenticate with the server for outogoing
mail?

Is that actual error message or you just deleted real e-mail address?

If you just deleted e-mail address then it looks like you have not restarted
IMC.

I have indeed, although like I said I'v since set the server to allow
anyone, authenticated or not, just so long as there IP is in our domain.

This is the actual error message, including the 'Adam Stark (E-mail)' bit.
That comes straight from the clients personal address book and how it
appears on the top of the message before it goes to the exchange server.
I would usually expect that the client changes all these display names to
e-mail address's when it does the post to the server. The server has never
stored the users address books or verified the recipient before (at least I
don't think so).

I'v removed no e-mail address's from anywhere, either server or client. The
odd thing is that it send to some people and not to others. I can't even say
that its certain domains because it simply isn't.
I'm seriously thinking of doing away with Internet mail protocal and setting
up exchange to use the exchange protocal. (Don't really understand why it
wasn't in the first place!). This is a last resort though so any other ideas
would be truly Ab Fab. Cheers.

Have you tried to send message with manually typing validated e-mail address?

I tend to say the problem is on client's end, in PAB.

Then don't even fight with that. Convert them to MAPI.
