parsing IMAP responses?

[Grant Edwards]

According to Google, the question has come up before, but there
doesn't seem to be much of an answer.

The imaplib module return values are mostly useless as-is:
they're just whatever string the server sent (or in some cases
a list of strings). You've got to parse them using the IMAP
syntax before you can do much with them.

Is there a library somewhere that impliments the IMAP protocol
syntax?

It's very messy. I don't know of one that's in distribution. I think
there's one buried inside a certain commercial product. I wrote one a
while back that is currently inaccessible (disk crash, need to get it
recovered) but it's not really useable. IMAP syntax is very very messy.
Are you trying to write an IMAP server?

It's very messy.

It sure is. You'd think something intended to be
machine-readable would be easier to parse.

That's what I thought based on my Google results, but I thought
I'd ask.

No, I'm writing a client, and I was a bit surprised to find out
that imaplib doesn't really parse the responses at all. Since
I'm writing a client I only have to parse the responses to the
commands that I actually send, but it still a bit messy.

nobody knows what the IMAP protocol designers intended...

(it's not quite as bad as Netscape's Mork format, but it's pretty close)

Maybe the "core" part of getmail could be reused, it seems cleanly
written.

Thanks -- I'll take a look.

IMHO, email is the most disgracefully badly spec'ced "application" in
existence: I'm sure the average modern-day scr1pt k1dd13 could do better.

SMTP: Have you ever tried to bounce processing? PITA.

POP: No virtual hosting support.

IMAP: You are in a twisty maze of passages, each slightly different .....

It's no wonder the spammers can ply their trade with such ease.
