Hi Webert -- Thanks for the quick reply and observation.

When I try "telnet localhost 143" I get the same result. It does connect but then the connection is dropped.

# telnet localhost 143 Trying ::1... Connected to localhost. Escape character is '^]'. Connection closed by foreign host.

I never get the "* OK [CAPA....]"

Thanks,

You won't have that "* OK [CAPA....]" message by doing telnet on port 993, as this is a secure port and the connection is encrypted. Either you need to use something as openssl or gnutls to test it that way, or telnet to imap port 143 (not encrypted).

Hi,

This is my environment:

SMTP: Exim 4.89 with Mailscanner 5.0.3

IMAP: Dovecot 2.2.10

At the moment I'm just trying to test out my Dovecot to check if
it's listening on port 993.

*netstat -tuln:* Shows that my machine is listening on ports 143
and 993.

*telnet localhost 993: *This is my issue, I get the following message:

# telnet localhost 993
Trying ::1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.

According to the wiki.dovecot test installation page I should be
getting this instead:

https://wiki.dovecot.org/TestInstallation
<https://wiki.dovecot.org/TestInstallation>


Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID
ENABLE STARTTLS AUTH=PLAIN] Dovecot ready.


When I run doveconf this is what I get:

# doveconf protocols listen
protocols = imap pop3 lmtp
listen = *, ::

Does anyone have an idea of what I'm missing here? Thanks.

Hi B. Reino,

These are my dovecot logs. It looks like this error pops up every time I run "telnet localhost 143"

OK. Can you post the output of # doveconf -n|grep ssl

Cheers, Bernardo.

Hi Bernardo -- Thank you so much! After I changed my input I also got an error when trying to test through telnet, but that was because I was missing the dovecot-mysql package as well. Thanks again, cheers.

I guess you didn't read https://wiki2.dovecot.org/SSL/DovecotConfiguration

Change ssl_cert and ssl_key so it reads like: ssl_cert =

Notice the "<" before the path.

The rest (ssl, ssl_cipher_list) is OK (but check if in the end ssl is "yes" or "required" and pick one).

Good luck! Bernardo.
