The only thing users should notice is a bunch of new certificates/keys:
- there is a new ssl certificate for IMAP, that you have to tell your client to accept
- once webmail comes up, there will be a new ssl certificate for https
- for those that use ssh on warchicken, there is a new ssh key
I will post any complications that arise here.
Update: Webmail should be fixed. There was also an issue with smtp authentication that was discovered and corrected this morning. Pretty soon we can turn off the old, noisy, power-sucking warchicken.
