[maildropl] Maildrop Dropping and Truncating Messages

[<dar...@ac...>]

Hello All,

=20

I have been using Postfix/Courier/Maildrop/Spamassassin/Squirrelmail for
a couple years now as a web based email system and it works very well
for the most part.

=20

The problem:=20

=20

It appears that maildrop truncates and drops messages a couple months
after a user account is active. Over the course of one day, messages of
all lengths and sizes are delivered without problems. The next day, the
end of certain message bodies are truncated and some are simply never
delivered. I have absolutely no clue why this happens, but I think I
have isolated the problem down to the maildrop piece.=20

=20

The install:

=20

I use the default versions of postfix and squirrelmail that come with
Fedora Core 3. I compile maildrop, spamassassin, and courier-imap. I
make NO modifications to any of the config files for maildrop and
courier-imap.

=20

The facts:

=20

Fedora Core 3

[root@cent ~]# rpm -q squirrelmail

squirrelmail-1.4.6-0.cvs20050812.1.fc3

[root@cent ~]# rpm -q maildrop

maildrop-1.7.0-1.3

[root@cent ~]# rpm -q spamassassin

spamassassin-3.0.1-1

[root@cent ~]# rpm -q courier-imap

courier-imap-3.0.8-1.3

The error condition - Message Dropped.=20

=20

Here is an example of a message that reports to be delivered by postfix,
but DOES NOT appear anywhere in my Maildir.

Here is an example of a logwatch report that is simply "cut off". Once
again, postfix reports the message is delivered, but maildrop has it
truncated.

I really do not know what to do anymore. If I can't resolve this, I'll
have to use a different system (which I don't want to do).=20
