Hello,

We have had multiple customers complain that legitimate mail from well-known providers (Hotmail, AOL, Yahoo, MSN, etc.) is being blocked.

After some investigation, we have determined that the SORBS DNS blacklist (dnsbl.sorbs.net) is improperly listing hosts, and causing these lost mail.

To avoid this problem, either disable the SORBS blacklist in your administration console; or change it to add to the spam score instead of blocking the mail directly.

Here is a screen shot that highlights the SORBS list setup to add to the spam score.

Cheers,
Joshua Thomas

SORBS are a PITA!

Best avoided in my experience - especially if you have business or customers in Eastern europe, Russia and Asia.

It would be nice if we had the ability to whitelist email addresses and the order or operation was changed check the whitelisted email addresses along with ip addresses and have KMS check these whitlists prior to rejecting anything.

I'm sure that this is an already known feature request...

Thanks,
Conn

Hello,

Fedora Core 5 (http://fedora.redhat.com/) was released today, Monday the 20th.

There is an incompatibility with the FC5 libstdc++ library and the current version of Kerio MailServer, which may cause a crash in WebMail.

Therefore we recommend you DO NOT use or upgrade to Fedora Core 5 at this time.

KMS requires libstdc++.so.5. This library must be installed in FC5 in RPM package compat-libstdc++-3.3.2.rpm.

Unfortunately, is appears that libstdc++.so.5 from FC5 is not fully compatible with Glibc 2.4.4 sed in FC5. This incompatibilty leads to infinite loop in btowc() function (crash due to stack overflow).

You can see the Fedora bug here: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=186410



Thank you,
Joshua Thomas

It depends on Fedora developers as there is a serious bug in FC5.

New kernel 2.6.16-1.2080 is published since yesterday, that will change something for the bug ?

For those looking for a production quality RedHat distro I would highly recommend CentOS. I run it on a couple of our Kerio mail servers without issue.
