I'm building a new server to replace an old one in production. I've never
had trouble in the past, but it's been a while and it is not going smoothly
this time. I've spent a week trying and not getting it going. I gave up
getting Cyrus-sasl to work, moved to Dovecot. Got farther but stuck now.
Eyes crossed. :)
This is on Centos 7, Postfix 2.10.1 from stock rpm, Dovecot 2.2.10.
I have my self signed certificates made and entered in main.cf and
/etc/dovecot/conf.d/10-ssl.conf I am no certificate guru, I think I have
them right.
I've checked everything best I can figure out how:
-----
test tunneled TLS connections to port 465
openssl s_client -connect tn2.myserver.com:465
Appears to work
-----
>From remote server
test STARTTLS connections on port 25 or 587 with:
openssl s_client -connect tn2.myserver.com:587 -starttls smtp
appears to work, shows a bunch of info and the certificate text. Nothing
that looks like errors except a line that says:
verify error:num=18:self signed certificate
verify return:1
-----
>From remote server
Tested my cacert.pem certificate with
openssl x509 -in cacert.pem -inform pem -noout -text
It did not ask for a PW, displayed contents, so I think that' s good (happy
to post output if it helps)
-----
checked if the cert and key match
(openssl x509 -noout -modulus -in /etc/certs/tn2.myserver.com.crt |
openssl md5 ;openssl rsa -noout -modulus -in
/etc/certs/tn2.myserver.com.key | openssl md5) | uniq
I only get one match so I think that' s good.
----
Telnet to the server and STARTTLS seems happy:

------------------
MS Outlook is happy using port 587 (SASL only I think) I can deliver a test
message. POP also works and it will retrive same.
But with Outlook set to use port 465 it will not work. Times out.
----------------
The maillog for the timed out test shows below. It gets to that last line
and just hangs.

Can someone see what I'm doing wrong? How to fix it? Hoping it's a config
error.
Please let me know if I've missed some piece of information. I'm a novice,
I'll be grateful if you temper your replies so I can take advantage of them.
Thanks very much
