Ok, but what's the big deal about them connecting to your server? Are they so many that you have excessive load or something? I think there's no reliable way to do what you want without client side changes. If the latter would be ok, though, a good way is WB's suggestion: Only allow incoming connections to 587 (and 465/smtps for the u$ clients) and block people which are not trusted (IP) or authenticated at MAIL FROM or RCPT TO. -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
