[solved] /tool e-mail fails with SSL=yes but works with SSL=no

RouterOS General
1

ROS 6.7

  1. /tool e-mail with SSL with login/pass SSL=yes to host=gmail server, - mail sends OK

2 /tool e-mail with SSL with login/pass, SSL=yes to host=XXX:465 server, - mail sends FAILS
ROS log: 15:52:24 system,e-mail,error Error sending e-mail : error connecting to server
I verified with /system telnet address=xxx port=465 that the XXX server accepts connection at 465 port.

so on YYY host I started: ncat -p 1465 -c “openssl s_client -quiet -connect XXXX:465”
then change the /tool email config to SSL=no host=YYY:1465 and other settings unchanged, then the mail goes out OK.

So there is some problem with SSL crypto client when ROS talks directly to XXXX host (works for gmail hosts)

How do I fix that ?



Edit: SOLVED
MT supports only STARTTLS, not TLS/SSL
xxxx:465 uses TLS/SSL
xxx:587 uses STARTTLS
