The web interface works fine on https -
      I think that SSL err might have been a red herring.
      
      So I downgraded to 6.1c-1 - the next previous version I found on 
ftp.netwinsite
      - and connections on port 587 are being accepted. I TOOK NO OTHER
      ACTION, no changes to surgemail.ini, and this email is being sent
      via port 587.
      
      ?!?

      I'm not aware of any changes between those versions that
        would cause that.  It appears to 
      be the same version of SSL and I don't see any ssl changes
        from our end.  
       
      It may be an expired ssl certificate (try removing it so
        surgemail regenerates a new one) also try another email client
        to see if that helps.
       
      Also check using https from a browser to the web interface to
        see if it is reporting anything unusual, it's the same
        protocol/library so it should give you the same problem.
       
      As a last resort you may want to try downgrading to that
        previous build to see if that repairs the problem, let me know
        if you want me to investigate further directly after you've
        tried the above...

        I'm in a Panic. 
         
        I upgraded from 6.2c-1 to 6.3c2-2 Linux 64, and I can no
          longer receive connections on port 587. I MADE NO OTHER
          CHANGES. 
         
        The only pertinent entry I can find in the logs is in
          mail.err:

        I did not change the (self-signed) certificate at all - it
          would seem SM is requiring a new setting????
