Please try to choose more descriptive subject lines (eg "problem with
sock.connect" or similar). That you want help is almost implicit, and
what the whole list is for.

Anyway, to your problem:

This usually means that either the host address is legal but incorrect
(there's no host/server listening with that address) or that the port is
incorrect and some firewall is _discarding_ your traffic because of the
wrong port instead of returning a nice "connection refused", which is
usually instant.

Fortunately you've listed your call:

So, I'll try that by hand here:

% telnet smtp.gmail.com 2525
Trying 142.250.4.108...
telnet: connect to address 142.250.4.108: Operation timed out
Trying 2404:6800:4003:c0f::6d...
telnet: connect to address 2404:6800:4003:c0f::6d: No route to host
telnet: Unable to connect to remote host
%

I'd say GMail are rudely dropping traffic to port 2525. Maybe try just
25, the normal SMTP port?

2525 is an alternative to 587, the standard TLS port. 25 and 587 work.

telnet smtp.gmail.com 587

The EHLO needs a domain. Port 25 is the same.

Yah. My point was more focussed on GMail's shoddy firewall practices not
returning connection refused.

Good to know. Thanks!

Port 587 is not the standard TLS port. Port 587 is the standard mail
submission port (i.e., a MUA should use port 587 when sending mail; MTAs
should use port 25 when relaying mails to other MTAs).

Traffic on both port 25 and 587 starts in plain text. The server can
indicate that it supports TLS and the client can then send a STARTTLS
command to start a TLS session.

If you want to start the connection with TLS, you can (usually) use port
465. Like 587, this is only intended for mail submission, not mail
transport.
