Delivery incomplete from gmail

What do you mean by "send a message via gmail" - are you trying to send an email with a Gmail account as the Sender?  Where did you find those log lines?

I'm getting a bunch rejected email too.

Gmail, Godaddy, Yahoo and a few others too

I think, but not positive, just getting into this, that it started with upgrade to V17

The error relates to STARTTLS on port 25 and a protocol error which indicates a setting on the email server

Problem is I haven't changed anything on the server

Its been in place a few years

I don't see anything in my server logs

error from one sender is:

  "TLS connect failed, connect to mail.interlakestamping.com:76.3190.90.42, STARTTLS proto=TLSv1.2; cipher=(NONE)"

error from another sender

  Diagnostic-Code: smtp; TLS Negotiation failed: generic::failed_precondition: starttls error (0): protocol error

error from another sender

Any help appreciated

Below is the email I sent to support

I was able to work around the issue by turning off advertise STARTTLS on our server for port 25, SMTP

I then had to turn it on for SSMTP.

Does not seem to be an issue for SSMTP but it is only used by a few of our EE’s (not gmail etc)

It is still a bug in the firewall as the SMTP email sessions are not connecting correctly when passing through the firewall

The firewall is also failing to log a connection attempt

After making the changes I now have log entries showing successful receipt and delivery of emails from gmail

Yeah I know, should be posted in XG firewall forum but I was redirected to this forum when I did a search.

Anyway,

  Many thanks to Harsh Patel, Sophos support.

He put forth a mammoth effort to try and figure out my issue.

He was knowledgeable and patient.

Glad this is resolved for you, Jake.  You've posted in the UTM Community, but you have an XG.  You ight want to post about this in that community.
