gmail imap and std smtp service

Hi,

I have a system when I use gmail imap to retrieve email and send email through an internal smtp server, that eventually forwards to Gmail. The internal server is used to manage mailing lists.
If I autosetup and then change the smtp setting to the internal server it does not work emollient insists on using TLS.
Not sure how to fix that

I don’t know what SMTP internal server you are using, but the below are the SMTP server settings you can use with eM Client to send.

SMTP
Port 587 = Force usage of SSL/TLS
Port 465 = Use SSL/TLS on special port (legacy)
Port 25 = Use SSL/TLS if available
