First of all, please keep answers on the mailing list only. Obviously I 
am subscribe and I don't need to get your reply twice, by list 
distribution and in addition to my personal address.

And top-posting is another thing you should avoid.

To your answer: I disagree and see that you have a false understanding 
of security. You want service protocol encryption (here for IMAP or 
POP3) from end to end. Nothing which breaks up encryption in between.

That's valid for any size of environment. You may judge the risk is 
tolerable in case you run you own small setup where you are the only 
user. But I replied to Mark's note where he wrote about ~100 clients. So 
he either running an IMAP service for clients - where it is 
inresponsible to not teach them about security and instead lower the 
protection to none - or administering a company network for which end to 
end service encryption is a must too.
