Hi all,

I am trying to send an email via SAS Studio 9.4 M6 and getting a warning saying "TLS cipher supports less bits than expected."

An upgrade is in the works; using port 587, local postfix or requesting the security team to allow weaker ciphers are not options.

Anyone have luck with any other workarounds?

Thank you!
