MailDaemon: possible SSL regression

[miqlas]

From one day to the another MD stopped to work and only shows the status window with the following:

a@b.com Could not connect to SMTP server cpanel1.rackforest.com:465 [Mon Jun 29 17:24:44 2020]
a@b.com Error whilst opening connection to cpanel1.rackforest.com. General system error [Mon Jun 29 17:24:44 2020]

Email address removed, for the sake of privacy.

Trying to connect to cpanel1.rackforest.com on port 465 with nc also fails:

# nc -vz cpanel1.rackforest.com 465
cpanel1.rackforest.com [185.43.206.2] 465 (urd) : Operation would block

also

~> openssl s_client -connect cpanel1.rackforest.com:465
connect:errno=-2147483637
~> error -2147483637
0x8000000b: Operation would block

Interestingly the same command works with other servers on Haiku. Not tested with other OS.

"Operation would block" error reminds me to SSL problems, so this is why i suspect SSL. Other devices (with different OS) works on the same WLAN. Booting earlier version doesn't helps, i went back till mid may, maybe a change at the ISP?

I don't expect any quick fix, but this is actually critical for me.

Running mail-daemon i nthe terminal returns:

Almost forgot: mails doesn't gets sent, and doesn't arrive.

Might be related to #15853.

Sorry, forgot the OS version string:

~> uname -a
Haiku shredder 1 hrev54368 Jun 28 2020 07:32:39 x86_64 x86_64 Haiku

Seems to be working again, no idea, what happend, maybe the isp fixed it.

As it seems others didn't see the issue, and it's working for you again, let's close this.
