GEAM already comes with a simple SMTP daemon and porting it to Windows is trivial. However, the real problem is that the syncronization issues between a mailer and a proxy smtp, where the latter should do all the crypto stuff is really hard. I once started to write one (IIRC, at least the pop3 part did work) but gave up on this because it will be too hard to get it right and if we eventually have a working thing it a) won't be usable for the average user because it is not intuitive to use. b) opens that path to a lot of security problems which can easily be expoited with social engineering methods Werner --z9ECzHErBrwFF8sy--
