I'd like to draw your attention to KB article: http://support.kerio.com/kb/511

The text of which follows:

Problem

You are seeing errors in your logs indicating a DNS failure, when checking against list.dsbl.org or unconfirmed.dsbl.org

or

You are experiencing delays when receiving emails, due to slow response times, or timeouts when querying *.dsbl.org

Reason

The Distributed Sender Blackhole List (DSBL) has been taken offline by the owners, due to their belief that the list is obsolete. As a result, all name server queries submitted against the list will fail. You can read more about this at http://dsbl.org <http://dsbl.org/>

Solution

In order to overcome the errors generated by the failed lookups, you can disable the two DSBL entries in the Blacklist setup screen.

Login to the Kerio MailServer Administration console, then select ;

Content Filter >> Spam Filter >> Blacklists

Untick the two DSBL entires

The way the DSBL sets their delay can cause the mailserver to delay it's SMTP greeting for over 1-2min. And this can result in time out, and losing emails.

Make sure to disable those 2 blacklists ASAP!

That explains the problems I've been having with slow/no sending for POP3/SMTP users.

Thanks!

i assume that the next update of the mail server will remove them from the list so that it eliminates the possible problem in its entirety?

Correct. Next KMS update will remove it automatically from the configuration.
