cyrus imap 2.x, sendmail and bulletin boards

[Travis Fitch]

Just wondering if anyone has pointers on how to get bulletin boards to w 
ork with cyrus imap 2.x and sendmail 8.12.x

I am using cyrusv2.m4, and I noticed that there are no bb definitions in 
it, like there is for cyrus.m4

Regs .. Travis
