Disabling TLS for qmail-send

    My server is unable to send mail to a particular remote SMTP server - mail bounces back with 'TLS connection failed' ("(error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol)"). I suspect the remote server is advertising that it supports SSL when in fact it doesn't (my server can use SSL when communicating with other SMTP servers fine).

    Is there a way to stop qmail-send from attempting to use TLS when talking to this host? I may even have to go down the route of disabling TLS completely, but can't find a way to do that.

    Any thoughts please?

    I really need to do this as well with an 8.6 system. I have looked all over for information on how to do this. If anyone can help or point me in the right direction it would be appreciated.

    I'm half way to finding a solution - I should have been reading up on qmail-remote, not qmail-send ...

    http://inoa.net/qmail-tls/qmail-remote.txt

    Going to try that shortly...

    I'm guessing this didn't end up working? I can't find any reference to notlshosts in the qmail-remote binary that Plesk bundles so I'm thinking they're not using that specific TLS patch.

    You need to switch to postfix; the qmail-send included with Plesk has numerous issues on today's internet; sslv3, dh keys <1024, all email goes out the first ip, etc.
