hi dude's.

Do any body knows how doe's ListServ arrange, sort or mannage the emails 
address dristibution? Is it sorted by email address alphabetically, or 
by domain name alphabetically too?
This is because our SMTP provider is telling us that ListServ is 
grouping the delivery by domain causing some servers (hotmail, yahoo...) 
rejecting our messages because they think we might be attacking them.

If so, is there any other way to configure it?

Thanks a lot and best regards
