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 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?

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 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, On 04/20/2017 10:41 AM, Webert de Souza Lima wrote:> 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). > > On Thu, Apr 20, 2017 at 11:33 AM, Alvaro Lacerda > <alacerda at cantella.com <mailto:alacerda at cantella.com>> wrote: > > 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?
