This seems to be less painful than I was anticipating... Besides
apache, I had to figure out how to boost the security on IMAP and POP
3 connections. I'm using Courier, so this was pretty simple... just
added the following to the imap and pop ssl config files:
TLS_CIPHER_LIST="HIGH:MEDIUM:!SSLv2:!LOW:!EXP:!aNULL:@STRENGTH"
I'm going to resubmit the server... hopefully it will pass this time.
But I wonder why the defaults for Apache and Courier are to accept
SSL 2, if it is so problematical?
