If a "newer" server works, then I guess the problem is due to differences in the TLS stack. or in the TLS configuration, or that the cause is some obscure data-dependent problem(*).

It certainly is time to start looking at upgrading this mailserver. It's Debian 10, which is EoL now. It's just been SO reliable that I've always put it off. This will probably be the impetus I need to do the upgrade instead of putting it off again.
Thanks for your suggestions, I really appreciate it. Kind Regards, Tim _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
