I was finding implementing IMAP a bit painful using the simple command structure that we used for POP and SMTP. IMAP is more of a mini line langauge than anything else. So I was going to write a parser with ANTLR but I found one as part of another project and its BSD license (essentially). It is a project called epost. I'll be messing with the parser a bit and if it all works out well I'll just use their grammar/antlr. That may mean ditching some of the donated IMAP code (sorry) which attempted to start us off by using the same structure as our SMTP/POP code. The good news is that while I may be putting the cart before the horse I think this will shave weeks off of our effort.
The BSD project is epost for those interested.
