Hello, In fact the right configuration is smtpd_discard_ehlo_keyword_address_maps = cidr:/etc/postfix/ehlo_maps.cidr
If the remote smtp server (Sender) has a buggy TLS, so I can refuse the use of STARTTLS by this server. So my problem is now solved. Thanks to all and sorry if I did not read the documentation, but I've no enough time at this time.

I think smtp_tls_policy_maps might work here. -- Stephen Carville
