...and the same applies for Dovecot 2.0.1 and Dovecot 2.0.13.
Am I overlooking something?

Hello,
I am trying to set up Dovecot 2.0.9 on Fedora 14. The problem I would
like to ask for resolution is that IMAP is not working when connecting
to the server from another network.
More precisely:
- POP3 is working entirely OK,
- IMAP is working OK when clients are connecting using local network
addresses, like 192.168.0.100,
- when a client connects from outside, thus using remote IP address, or
even from the server itself using the remote IP address of the server,
the following happens: the client correctly connects, but the server
sends no greeting (neither the configured login_greeting nor the server
IMAP capabilities) and does not respond to the commands. In the server
log, I get the following record a while after trying to connect (and
actually trying to login):
Jul 08 23:24:16 imap-login: Info: Disconnected: Inactivity (no auth
attempts): rip=<remote-server-address>, lip=192.168.0.100
Both routing and firewall are OK. The client really connects to dovecot
(hence the log message), as seen from a telnet session:
Trying a.b.c.d...
Connected to example.tld (a.b.c.d).
Escape character is '^]'.
(and then nothing else)
The most confusing for me is the fact that POP3 is configured quite the
same and works fine, as well as IMAP on the local network. I tried to
change address in the inet_listener imap configuration, but if a wrong
address setting was the cause, the client would not get connected at all.
As I have spent a pretty long time unsuccessfully searching for a cause,
I am asking for some help.
Thanks for your time,
Ondrej Bouda
