Microsoft mail server emails rejected - HELP!

[coolemail]

An external (not hosted by us) domain is using microsoft messaging to do their spam/virus checking of emails. When they send to our hosted domains, the emails are rejected:

In bold above is the reason for the REJECT.

Please can someone help and tell us where the greylisting rules are and how we can disable/amend the one at fault.

The link in my other message appears to show the identical problem. The link was:

I know it was 9.x in that post, but I rather suspect you would do the same thing in 10.x. At any rate start with finding grey_listing then running it with -i as mentioned in the post. It will probably be in a different location. If that comment exists and works, then use the

./grey_listing --update-server -domains-blacklist del:"dsl|pool|broadband|hsd"

Or switch it off completely - Settings -> (Mail) Spam Filter Settings, untick enable greylisting

thank you so much faris,

I had not done anything because it was saying it was for Plesk 9 when I tried to cat the file. But removing that rule has worked. Like the other person in the other post, we have got people who are using microsoft messaging and their "pool" as part of the mail server was causing them to be rejected.
