Re: [suse-security] Plaintext passwords IMAP please!

Thanks Maarten,

I thought I was going mad!

I agree that a core function like this shouldn't be changed in such an
unhelpful way.

IMHO this is supposed to be why we use SuSE rather than suffering the random
decisions of package maintainers and even of IETF bodies?

I am totally unfamiliar with SSL, I've resisted it just out of laziness - I
have enough to do with being a Windows dev. and part-time linux sysadmin

All clients will be Outlook Express but I'm guessing that SSL is more of a
shared library thing on Windows, i.e. registry settings, etc. to allow
clients to access a server with SSL where certificate is self-certified.

So anyway it's worth a go; can you give me a quick idea of how I set up SSL
on my linux box, create a certificate and then get imapd to use it?

Alternatively a well-written, simple HOWTO would be fine!
