Mail server Help please!

[golddiggerguy]

Just had a call from a client we're building a site for but they have their email hosted elsewhere.

Their IT guy is away on his Hols and called me for help.

They have a mail server thats spitting out emails (45'000 in one week) to one company and need a bit of help to stop it. (or their ISP is cutting their connection)

I know it will be a trojan of some sort, but scanning it on Bootup will bring it down for hours. Not good.

Is their a way to add a domain that the server does NOT send to. i.e

the server can't send emails to @123ABC.com as a temp measure?

Any help very welcome!

what mail server is it?

are they real emails your sending? have you checked they arent NDR messages - non delivery reports? Sometimes you can turn off this feature and your mass of outgoing data will stop.

It's running a set up on 2 machines mail guard and Microsoft exchange!

Then 40+ machines using them for mail. it could be the server or users with the issue but have made altenate arrangments and will diagnose thursday.

Cheers guys
