I need to filter some email accounts at ourdomain to accept email from @
ourdomain.com only. My hosting company said this would have to be done with
an exim filter, but I have not been unable to find anything on this. They
said they would install it and test it if I gave them the filter. I'm sorry
to be so ignorant, but I cannot find anything I understand through
searching. If anyone knows what commands would work to create this filter,
I would appreciate the information. I'll take that and slog through with a
test account.
