No thoughts on these anyone?

Related to #2 below, if the the MCP SpamAssassin times out, the email is
quarantined as MCP!

Oct 11 14:05:37 cheetah MailScanner[21950]: Message i9BI347P027207 from
207.250.170.169 (electionshirt at zippedemail.com) to jasper.k12.ga.us is MCP,
MCP-Checker (MCP timed out)

[root at cheetah mcp]# pwd
/var/spool/MailScanner/quarantine/20041011/mcp
[root at cheetah mcp]# ls i9BI347P027207
i9BI347P027207

Have thes bugs been fixed in beta releases?  They seem non-minor as I've had to
stop using MCP.
