After upgrading my test box from 7.0.0 OSE to 7.0.1 OSE I'm getting the following issues.

1> If I just restart with all conf files in place:
fatal: unsupported dictionary type: chash

gets logged and no SMTP banners are ever displayed

2> If I remove /opt/zimbra/postfix/conf/main.cf, I get a slightly smaller main.cf generated, but still has the offending "chash" line in it.

The "chash" line in question seems to be:
virtual_alias_maps = proxy:ldap:/opt/zimbra/conf/ldap-vam.cf chash:/opt/zimbra/postfix/conf/virtual

when I edit the line, for example removing chash.*$, it gets regenerated with zmmtactl restart and the problem remains.

I've tried googling the internet and grepping the file tree and can't find any reference to a map type of "chash" at all, much less any actual files from Zimbra that include the text string "chash".

Please Advise.
