courier-imap fails
I've just upgraded my VPS from Wheezy to Jessie.
Most things work fine, but my mail service has died.
The only clue is in /var/log/mail.info:
imapd-ssl: couriertls: accept: error:14094417:SSL
routines:SSL3_READ_BYTES:sslv3 alert illegal parameter
It turns out that this was reported in bug #787579, which I think should
have been resolved by now. Googling suggests a work-around: DH_BITS=2048
mkdhparams, but this seems to have little effect. I'm not sure what format
a PEM file should take, but my dhparams.pem is only 201 bytes, which seems
a bit small.
Anyway, can anyone please suggest any remedy, please.
