Cannot connect to IMAP server

Hi

I tried to log onto my email but can't connect to the IMAP server. I can send out email, however. I can also use webmail. Is anyone else in the TN area having IMAP issues? I also tried to ping the IMAP server; it timed out.

Thanks

KT

At least in my market, imap.comcast.net resolves to imap.ge.xfinity.com. It appears it does not respond to ICMP, so my ping doesn't work either. imap.comcast.net may also resolve to something else in your market. I don't know how they do DNS/load balancing and email server instances. It's possible it is currently broken in your market. If you can't see the server at all, there's no chance.

You can however test the imap server with openssl from a command line if you have that installed. Windows - try WSL (windows system linux), it's a feature option you can enable on win 10/11 (search for WSL for help on that). Built into Mac and Linux. I don't know if by default it's installed and accessible from power shell. Try the command:

Command:

openssl s_client -connect imap.comcast.net:993

Result:

...

(bunch of cert stuff)

....

* OK [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE LITERAL+ AUTH=PLAIN AUTH=LOGIN AUTH=OAUTHBEARER AUTH=XOAUTH2] Dovecot ready.

What it means:

Your default system is setup for TLS 1.2 or can negotiate it, so that's good. You didn't have to specify TLS version on the command line. Notice:

SSL-Session:
Protocol : TLSv1.2
Cipher : ECDHE-RSA-AES256-GCM-SHA384
Session-ID: 04DA8602BB1BC194E......(etc)

You are able to parse the certs and the machine is responding. Dovecot is the auth server, so it's waiting for additional commands.
