So,
If you want to stop TLS for a particular domain as QMT will encrypt via
TLS all SMTP traffic unless 1) a mail server does not support it, 2)
incompatible encryption (your case), 3) you prohibit it for a certain
domain (following example), do the following:
1) # nslookup -type=mx 'domain.tld'
domain.tld mail exchanger = 0 mx.domain.tld.
1) mkdir /var/qmail/control/notlshosts/
2) touch /var/qmail/control/notlshosts/mx.domain.tld
This will stop all traffic to domain.tld from being encrypted.

I'm not sure it will work. It installs side by side with old rpms
openssl and openssl-devel. I'd try creating the notlshosts/<fqdn>
first, and let me do some experimenting.

In fact, here's a binary
https://centos.pkgs.org/5/epel-x86_64/openssl101e-1.0.1e-11.el5.x86_64.rpm.html
and the how to
1. Download the latest epel-release rpm from
http://dl.fedoraproject.org/pub/archive/epel/5/x86_64/
2. Install epel-release rpm:
# rpm -Uvh epel-release*rpm
3. Install openssl101e rpm package:
# yum install openssl101e

That's the issue. TLSv1.1 & TLSv1.2 are only support in openssl-1.*
You could disable TLS for this email address
(https://serverfault.com/questions/562234/disable-starttls-on-qmail-for-outgoing-messages).
Or, you could upgrade manually openssl on CentOS 5
(https://miteshshah.github.io/linux/centos/how-to-enable-openssl-1-0-2-a-tlsv1-1-and-tlsv1-2-on-centos-5-and-rhel5/).

What version of openssl is on your host?
# rpm -qa | grep openssl

I am getting this failure when trying to send mail to one
email address.
The error is TLS connect failed: error 140770FC: SSL
routing: SSL 3_GET_SERVER_HELLO: unknown protocol. It
appears your server wants a TLS or SSL connection or
certificate.
I am running a qmail toaster on Centos 5.11.
How can I tell what version TLS I am using? The support
person on the other end says they do not accept version
of lower than TLS 1.1 or 1.2.
Thanks ,
