I'm running into an issue where some e-mails are not being received. I appear to be able to send to them, but when they send or reply they get:
The following addresses had permanent fatal errors
(reason: 403 4.7.0 TLS handshake failed.)
Hi. This is the qmail-send program at mail.xxxx.com. I'm afraid I wasn't...
TLS not available: connect failed: error:000000000:lib(0):func(0):reason(0)
Is there anything on my side I could look at to resolve the issue?
I've been getting a number of complaints about missing mail coming in to our
server. The errors these folks have been getting is (reason: 403 4.7.0 TLS
handshake failed.) The messages try for a time and finally fall out of the
Mail Server's Queue. Any ideas?

I'm not a sendmail expert, but from some quick research I discovered that this may be a problem with your server erroneously detecting sending servers as requesting a TLS connection. The recommended solution is to disable TLS:
[code:1]##Add this entry in server.tab:
Then ask anyone who has had problems sending you email to try again.
