Ongoing notification problems

Dear all,

out site has a newletter subscription built into it, which has
been working very well until just recently. I'm hoping
some of you will be able to help me iron out the lumps.

What we have is actually very simple. People create a sub-tree
notification event on a particular node, and recieve the newsletter
when that node is published. As I said, this has been working very
well until recently, when suddenly the notification stopped being
sent.

This is generated at the command line:

Running cronjobs/notification.php
Starting notification event processing
postdrop: warning: stdin: illegal length 3174, record type 78
postdrop: fatal: uid=1000: malformed input
sendmail: warning: premature end-of-input on /usr/sbin/postdrop -r while reading input attribute name
sendmail: fatal: akelly(1000): Error writing message file
Done

A similar message can be found in the mailer log files.

What I'm gathering from the (very little) I've been able to find
in the forums is that postfix is choking on an oversized header.

There are currently only about 200 subscribers at the moment, but once we're
out of beta we're expecting maybe 50x that amount. Is eZ really not
capable of sending notifications to more than a few dozen recipients without
blowing things up?
Anybody seen this before and know how to fix it?

Very, very grateful for any assistance, and much thanks in advance.

Just in case anybody else ever bumps into this problem, it turns out
that Postfix is the bad guy. The current Postfix package in Debian Sarge
(as of this writing) contains an unresolved bug which hammers long headers.

Feed sarge a fresher Postfix from backports and the problem is resolved.
