I been getting a lot of bounce complains with this error. I had tried reinstalling Exim 4 twice, and a few other things.

Also I started seeing a lot of this error in Exim Main log

2004-10-29 03:39:03 unexpected disconnection while reading SMTP command from (student.lu.se) [210.106.60.163]


I had also been getting some unroutable complains to hotmai.com, yahoo.com. This started about 2-3 days ago.

Anyone got the same problems, or know how to rectify it?

Ya. I found that thread, and had patched Spamassassin. Seems to be working so far.
