This solution (using isp smtp servers) is not a good solution if Edinilson is the mx for its customers, because more and more servers use spf or dkim, .... that could reject the isp server not registered as an 'autorized' smtp server for the sender domain (and autorizing the isp in the spf or dkim dns records open the door to any isp customers to use the original sender domain ....)

IMHO you should let them use their ISP's smtp-server (option "DefaultSMTPGateways" in server.tab), especially if they have a dynamic ip. Is'nt that the solution you are looking for, or am I missing something? :-S Best regards, Tjeerd On 12/11/2007, "Edinilson - ATINET" <[EMAIL PROTECTED]> wrote: >These users are (at this moment) using our smtp server to send their >messages.
