gnutls_handshake: The Diffie-Hellman prime sent by the server is not acceptable (not long enough).
Looks some default settings have changed? But which - and how do I override it?
DH primes come in different lengths - I don't know anything about mutt, but somewhere there is bound to be a config file that also says
... which lengths to accept. It sounds like your server is sending a 'short' one, which some setting in mutt refuses.
If you google the error message, there are plenty of hits, but many are quite old.
Yes, did that (of course), but reports from >10 years ago are not too helpful, and so far I didn't find one that tells me where to change what :(
Sorry, yeah I agree, thought I would mention it anyway.
But as I said, mutt hasn't changed, libgnutls30 has (3.6.15->3.7.1), but doesn't have *any* configuration files...
Guessing wildly - so somehow the TLS library increased the minimum standards, and requires longer DH primes, probably 1024. I know this is a cop-out, but maybe contact university IT support and ask them? For e.g. postfix and dovecot, we have DH primes length 512, 1024 and 2048, rebuilt every day. -- Per Jessen, Zürich (0.6°C) http://www.cloudsuisse.com/ - your owncloud, hosted in Switzerland.
