I've seen this for 3 reasons: blocking ports other than 80 MITM of all mail connections allegedly to try to do spam filtering, but with good certificate hygiene the connections will fail (sending) spam filtering on submission side due to random addresses being in blocklists. This is arguably a bug and should be bypassed for authenticated senders. The fix for 1/2 is to add socks5/tor support to k9 :-) -- -- You received this message because you are subscribed to the K-9 Mail Users List.
