Re: List owner needs help dealing with mail loop

[David W. Tamkin]

Jim suggested to Mitch,

| If possible you might also just setup your SMTP server to deny incoming
| email from the rr.com domain.  That at least will help the short-term.

If you don't have access to do that, or if you have people with legitimate
posting rights sending submissions from the rr.com domain and you want to let
them continue posting, you could instead configure the list to moderate every
post whose headers (other than Subject:) mention rr.com.
