[Exim] SSL3_GET_RECORD:decryption failed or bad record mac

So, my port 26 SSL escapades have led me to another puzzle. If I use
Mail.app on port 25 with SSL, sending works great. If I use Mozilla
Mail 1.2 with the same settings from either an OSX or a FreeBSD
machine, I get the following error in Exim's mainlog:

2003-02-16 22:06:44 TLS error on connection from
lilbuddy.antsclimbtree.com (mrtoads.com) [216.27.183.129] (SSL_accept):
error:1408F455:SSL routines:SSL3_GET_RECORD:decryption failed or bad
record mac

Interestingly, I also get the same complaint with imapd (uw) on that
server (this is an OSX Server box) using Mozilla Mail, but not
consistently. It will work once, then fail.

Even more strange, I don't get these errors using the same clients but
connecting to my FreeBSD server, which is running a nearly identical
setup --

FreeBSD server
--------------
Exim 4.12
uw-imapd 2002.332
OpenSSL 0.9.6g

OSX Server
----------
Exim 4.12
uw-imapd 2002.336
OpenSSL 0.9.6e


I'm guessing this is an openssl configuration issue. Has anyone dealt
with this one? Thanks.
