you can turn off encryption to that host

2048 bits ought to be enough, I would think. Most of the references to
this problem that I was able to find suggested that it kicked in at
768 bits and smaller. So maybe it's the remote server.
The remote is e4.echonyc.com (108.60.149.50).
Where's the Diffie-Hellman key used by qmail stored on a
CentOS/qmailtoaster server?
Thanks,

hmmm.... Ours is 2048 bits.
What's the remote server?

What QMT/CentOS versions?

My new toaster delivers mail just fine to almost all hosts.
However, with one destination host I get the error:
TLS connect failed: error:141A318A:SSL routines:tls_process_ske_dhe:
dh key too small; connected to x.x.x.x
I'm not going to try again ...
The question is, which host has the undersized Diffie-Hellman key?
Is it my server, or the remote host?
If it's my server, how do I generate a larger DH key for qmail to use?
If it's the other server, how do I tell qmail to accept a lower
level
of security or no encryption at all for this particular destination?
Thanks for any advice,
Angus
