cdosys.dll issues via port 465

[MorrisC]

Suddenly my cdosys mails can not use port 465 over SSL......Is it related to the fact SSLv3 is disabled or something, both the client and mail servers have SSLv3 disabled...or my cdosys.dll is corrupted....

the error message is -2147220973The transport failed to connect to the server.
I can telnet to port 465 of my mail server

*It appears that CDOSYS.dll does not support TLS by design. Therefore, need to find another SMTP mail compoents to replace it if using SMTPS.

Hi,
I found out a similar situation when I patched for poodle vulnerability, but that was on linux, but patching Qmail was giving the error, but never found this one on the Windows. Can you please tell what mail server you are having on your server mailenable or smartermail? Not too sure, but check if below link is of some help.
