You mean your IMAP server doesn't implement quotas? Let me give you a URL to our sales page ... And with the push to thin clients and NC, where else are you going to store that mail?

I'm not sure how IMSP helps with virtual domains. This belongs a lot closer to the MTA. IMSP isn't really useful until you've drilled down into the context of an authenticated (IMAP) user. As for filtering, SIEVE is getting close to being reality (there are three prototypes running that I'm aware of). Also, what's a "full" IMSP implementation? There never was an RFC issued. The Cyrus and SMS IMSP servers are as "full" as it gets, being the only two released IMSP servers (that I'm aware of). > Basically, it's an interesting "also ran" that won't displace POP3 > any time soon until its flaws are noted and corrected. I'm going to take great pleasure in quoting that back to you in a couple of years :-) My prediction is that IMAP is going to displace the majority of POP3 implementations over the next 2-3 years. POP3 just can't handle the mobile community that represents more and more of the e-mail users out there today. Now, to add something FreeBSD related, I've been pushing for ESYS to do a port of our servers to FreeBSD for a while now. We've had a couple of requests for it, but not enough to justify the cost of adding another platform. If there's anyone out there who would *buy* *a* *copy* of Simeon Message Server if we did a port, please e-mail me directly. (http://www.esys.ca for more info on the server product.) --lyndon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
