First of all, let me tell you how great of a product you have here. I have been tinkering with setting up a mail server for about two weeks now, and editing postfix and dovecot conf files is very tedious, and I never could get authentication to work correctly.  That is about the time I reimaged my hosted server and found your site.  What a painless install!  I have two issues, however.  First, Thunderbird mail client wont send mail through a secured port.  Any attempts to set port to 465 or 587 fails to communicate with server, and Android fails all the way around.  Vanilla install, open source edition.  I would love to pay for a pro version, but without these working, I can't justify this.  Any ideas?  Sorry if this is posted in the wrong section too btw.
