#162089 — Dovecot Problems?

I can no longer log on to my IMAP server from my Android. I can do so from 
kmail but even the URL is translated to localhost. Using k-9 mail on the 
android.

I have dovecot listening to *,:: (both ivp4 and ivp6)
I have tried with and without ssl,tls, neither works

I am not sure when it stopped working, dovecot upgrades or new router. The 
desktop ufw is set to allow all out and 143 in for all the combinations.

The router's port forwarding is set up the same way.

Should work.
What else do I need?

Perhaps stating the obvious, but have you had a look at the dovecot logs?
Can you spot your android's login attempts?

So it seems that the Android client isn't even succeeding in contacting the
server.

You happen to have some tools on Android like netcat or (gasp!) telnet?
Sorry I'm not very knowledgeable in things Android (or mobile).

Presuming you're running stable, I've got 1:2.2.13-12~deb8u1 running and
login from Android clients (K-9, Android 5 and 6) works just fine. I
would suggest using tcpdump to see how far the packets are getting.
Also, IMAP/SSL (as opposed to IMAP + STARTTLS) runs on port 993—make
sure you're not blocking that.

You could also use a telnet client on Android to test, by telnet'ing to
the IMAP port. Some trivial IMAP commands to try are "tag capability"
and "tag logout". Tag can be any tag, including "tag".

Is kmail running in the same host as Dovecot? That's the only way I can
think of that kmail is working with localhost as the IMAP server (or a
*very* broken entry in /etc/hosts).

If you only allow 143, IMAP over SSL will not work. It uses 993.

You are a little short on details. What error message do you receive
from K9?

Cannot contact server.
If I take domain out of hosts, same for kmail.
Using 143, startls on both.

Has to be the port forwarding but this is all very straightforward.

Progress. Assigned a static address in the router. This gave me 
communications.
K-9 kicked at the certificate so I took off starttls
Then it worked.

So I need to update the certificate. How do I do that (or where do I copy the 
files on the phone)?
