In general, you are right, of course. But the code is merely 60 lines 
and contains no heavy logic. The only SSL-specific stuff is a single 
call to SSLOpen(), the rest is more or less the same, with only some 
protocol specifics, esp. the rereading of the server's capabilities. I'm 
not sure if creating a new function that has to fulfill all the needs is 
that good, but I didn't look that close at the code. pop3.c contains 
just the same code, btw.

Sure, "fetchdomains" works as before. This is only the first hunk of the 
patch, so it could be easily removed.

AFAICS smtp_mode is used in logging, to get the char, or in comparisons 
with the macroes SMTP_MODE and LMTP_MODE. Should be not too hard to change.

Oh. Ok. Any reason for that? (Not that I want to start a discussion on 
tabs vs. spaces.)
And how do you tell vim (which I happen to use, too) to use this style?

Well, it's definitely not much compared to your efforts. So, many thanks 
back :)
