Gmail TLS problem

Postby Redkite » Wed Apr 08th, 2015 11:38am

Mailtraq Version: 2.xx.x.xxxx

Hi some of our clients can no longer send us emails as they are using Gmail and it seems not to like Mailtraq's Secure email solution.

We do not see it in our logs bu a client sent me their rejection by fax.

It basically states.

Technical details of temporary failure:
TLS Negotiation failed: generic::failed_precondition: starttls error (0): protocol error

On googling this i found quite a few forums with a similar problem using gmail and they had to turn modify settings i.e.

"restricting to accept only TLSv1 and TLSv1.1" and then it works?

Anyone any ideas as it is causing some headaches as some of our big clients can not send us emails?
