[webmin-l] Weird mail loop with catchall address

[Barry <we...@i1...>]

I am getting this message on a bounced email I send to a domain I am 
hosting - in theory it sould be redirected to a catchall address:
---------------
SMTP error from remote server after RCPT command:
host domain.com[xxx.xxx.xxx.xxx]:
554 5.0.0 rewrite: excessive recursion (max 50), ruleset canonify

---------------
Using Virtualmin GPL, v 3.31 on Centos 4.3 and sendmail.

- Domain has user "cat...@do..." to catch all the extra cruft: 
the pop3 login is catchall.domain.com
- additional email addresses nthat user's page is "@domain.com"
- if I click onthe edit email aliases button on the domain page of 
virtualmin, then "all mailboxes" are set to go to the catchall address.

Clearly this is isn't working. Can anyone advise on how to set it up 
properly?


Thanks,

Barry
