Zitat von Viktor Dukhovni <postfix-us...@dukhovni.org>:
On the other hand, some Exim MTA SMTP clients (patched by a well-meaning, but under-informed Debian maintainer) don't support DH primes shorter than 2048 bits.
I had trouble to receive messages from those sites too. I changed smtpd_tls_dh1024_param_file to use a 2k dh key at the mx server. That solved the problem ... Andreas
