By the way, while it is possible, I think the likelihood of spammers 
going to the effort to retrieve packets to use your server for spamming 
is extremely low.  I have never heard of anyone going to the effort to 
sniff packets simply to spam on commercial servers - none of the big 
commercial servers use SSL for regular email transactions - Comcast, 
SBC, and so on - and they have a lot more at risk than most of us.  
Also, it is a potentially pretty big bust these days since once they use 
an ill-gained password they have stepped over the law, so if they manage 
to cause damage with it they might be tracked down like dogs (with your 
help, of course!)

Lastly, SSL is not very efficient since it takes time to encrypt and 
then decrypt.  Personally I would only use it for transactions that are 
required to be secure, not for daily emailing.

Anyway, if you still want to use it, I would try updating your openssl 
either to the newest version or to 0.9.7e (which I know works on my system).
