Could you please unblock our server with ip 81.10.224.220 from your blacklist! We do not know why we are blacklisted - a virus-check on our system showed no infection!

We are a academical institution and are really dependent on our mailserver!

Thank you!

Your exchange server is being abused by spammers using the SMTP/AUTH exploit:

It also seems to be a recurring problem that might have never been fixed properly:

81.10.224.220 listed in bl.spamcop.net (127.0.0.2)

Causes of listing

System has sent mail to SpamCop spam traps in the past week (spam traps are secret, no reports or evidence are provided by SpamCop)

Additional potential problems

(these factors do not directly result in spamcop listing)

Listing History

In the past 60.6 days, it has been listed 6 times for a total of 17.2 days

Also note that there is a history of SPAMTRAP HITS that goes back to August listed elsewhere!

Here is a recent example:

So, the problem should be fixed! The abused server hat a weak security level because it was intentionally used only for internal mailing. The security problems should be fixed now, nobody will receive spam via the server!

Will the server be removed from the black list automatically after 48 spam-free-hours? If not, where should we write an email to?

Thanks for your help!

You could start by looking at the FAQ or the duplicate Pinned entry "Why am I Blocked" .... you could take the time to read the other (seemingly endless) Topics started in the last couple of days alone with the similar Topic Title of "Unblock Me ...."
