Happy Thanksgiving, Team:
Hoping everyone had a wonderful Thanksgiving Day and your celebrations included family and friends - no matter what your definition of family might be.
Hoping someone might be able to help me with the following situation:
We have a new customer, a major pet supply wholesaler, out of the West Coast, with whom we are experiencing difficulties making TLS encrypted connections to SmarterMail to send e-mail confirmations from their custom CF ordering system.
OUR END: We are running SmarterMail Enterprise 14.4.5802.27097 - SB - a special build.
We have ZERO issues with any other customers:
- no problems with TLS connections
- no problems with NON-TLS connections
The customer's MAIL services in CF are setup as follows:
COLDFUSION 10
SMTP SERVER: securemail.chicagonettech.com
ENCRYPTION: TLS
PORT: 587
AUTHENTICATION: via a valid username (user@kingwholesale.com) and password, known to be properly working and used by their order processing department.

When a connection is made, from the customer's CF shopping cart, I get the following error:

I even went so far as to WHITELIST the IP and server, and still got the following error:

In as much as our contracts with our government agencies and hospitals prohibit the whitelisting of any client's IP address or e-mail, I removed the whitelisting immediately after the tests were completed.
Thanks, in advance, for any assistance you might be able to provide regarding this frustrating matter!
