Sometimes I can't help but think that smartermail is a spin-off of Microsoft to keep people delusional that there is life outside exchange, that is to gain clients who hate exchange licensing etc..
this is thread for example should have received thousands of reviews but received none!
pgp is so very old but we the smartermail clients asking them to implement it finally..
after I reported so many times that the shared calendars do not appear in mobile GUI of smartermail and iOS and androids, I receive no traction except empty promises two years ago!
still to this date it doesn't work. Disappointing
