Interesting point, after some googling, I think you are right, and as 
long as we have set "disable_plaintext_auth = yes" (and we have that) we 
should be fine keeping 143 open. Right?

One doubt I had: "disable_plaintext_auth = yes" sounds as if only the 
authentication part is secured, and the rest is kept plain text, whereas 
with 993/SSL, *everything* would be encrypted?

Or am I missing something? (then perhaps someone can point it out?)

Thanks,
MJ
