Hmm I hadn't read that.  I was aware that doing it in a high volume 
scenario was problematic, but was under the impression that an 
occasional delivery here and there was theoretically possible.  Its 
pretty amazing since I test it manually and I can send to either one or 
the other and replication happens correctly; however, when the stupid 
logrotate message gets sent on the slave within seconds of a similar 
message being sent on the master, things die.

People that use replication as a quasi-hot standby server in the case 
the master goes down/needs maintenance etc, etc, how do you deal with 
locally generated mails that will eventually get delivered to a cyrus 
mailbox on the master to which this is the slave?
