They use an encrypted data transport. Ports 143 and 110 are (unencrypted) imap and pop respectively. My "astute provider" comment is directed at whoever you are using as your mail service provider (the operators of your sending and receiving mail servers). K-9 supports pop3s/imaps very well, and I believe in recent releases has dropped providers from the auto-setup list who don't do secure transport. Gmail does imaps/pop3s, so if you're using straight imap/143 pop/110 with them you should switch to the secure transport protocols. My initial concern was raised by your (new) seemingly unauthenticated send ability with your (non-gmail) provider. If they moved from authenticated to unauthenticated send abilities (which your initial message seems to indicate) there would seem to be a bit of a lack of understanding of things mail. If they support imaps/pop3s, start using those protocols, but the unauthenticated send ability means that it's probably just a matter of time before spammers find this and the host gets blocked. - Richard -- -- You received this message because you are subscribed to the K-9 Mail Users List.
