Please do not send copies to my address - I read the list, and it is
confusing (to me at least :).

Of course not - that's why there was a smiley.

I know. I also never claimed that the IMAP user base is insignificant -
it's just not big enough to register on Hiroyuki's radar, and Colin's
figures substantiate that much better than my assumptions.

Where did I say that? It was a quip, for crying out loud - and it even
had a smiley for the humor-challenged among us :-)

I did not say that - I said that _if_ you use IMAP only to download
your mails to your machine, _then_ it had no advantages over POP3.

Which is why I do just that.

Yes - but if you're using a server that you do not control, and you
want to access it via IMAP (which has as purpose to leave the mail on
the server), server-side filtering is not optional.

Take care,
