Hi all, I wonder whether I can prevent outgoing "bulk e-mail". A disgruntled leaving employee was threatening sending mail to all customers. (It did not happen but management was very unhappy and asked what I could do against it, from the technical side). I have a postfix mail relay (upstream going to the provider) but I cannot see a way of telling it "reject all mails with more than 50 addresses in the header", as an example. We have a special "list server" to fascilitate legitimate sending to many recipients at the time. It is bypassing this relay - so I don't have to worry about it. Thanks for answers Peter
