Incoming mail bouncing

[icam1987]

I hope someone can help me with this.

We have had wingate running on an XP machine for about 4 months. There do not seem to have been any problems up until recently but now a great deal of mail that people send to us is bouncing back. There is no other software running on this machine for virus protection/firewalls/spam.

We have about a dozen mailboxes on various client machines and some mail is still getting through with no problem. However some of our customers are reporting that they are receiving mail delivery failures and this was also the case when I tried to send from a yahoo address.

The delivery failure is as follows:

Hi. This is the qmail-send program at yahoo.com.
I'm afraid I wasn't able to deliver your message to the following
addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<xxxxx@xxxx.xxx.xx>:
Connected to 217.40.147.177 but greeting failed.
Remote host said: 2005-08-27 16:17:28 Failed to open configuration file
/etc/exim/exim.conf
I'm not going to try again; this message has been in the queue too
long.

The only thing I can think that has changed is that a couple of weeks ago I finally got Kaspersky registered properly and updating itself (we had the problem with the license file). Could this have made any difference?

I'm afraid I am a bit of an amateur so I don't really know where to start with this. Any help would be greatly appreciated.

Cheers

Do you know why the exim.conf file is not opening? Are you running Debian linux? ref: http://www.exim.org/exim-html-4.40/doc/html/FAQ_25.html

We are not running any type of Linux. Literally just wingate on XP.
I wasn't sure what the exim file was so I tried a search for it but there doesn't seem to be one on the PC at all.

I have had a bit of a breakthrough and I believe it is to do with an MX record that was pointing an IP that we no longer use.

I hope if I change the MX record with our ISP to look at the domain I have setup in Wingate with the external IP of the Wingate machine it should work.

If anyone thinks otherwise let me know asap as if it brings down our whole system I'm really going to be in trouble.

Cheers
