I don't understand. Either the Mailman server is on the private network or not. If other servers on the network are looking at where mail originates in order to determine whether or not to accept the mail, I would expect them to be looking at the IP address of the sending server or possibly things like the domain of the envelope sender or Received: headers in the message. The last thing I would expect them to look at is the From: header of the message. And, even if they are looking at From:, you seem to say that the original sender whose address is in From: is also on the private network. > I do not have access to change the configuration files unfortunately so > custom handlers will not work for me. > > It is a real shame that mailman does not allow you the option of setting up > anonymous mode with separate options for the email address name and reply to > fields. What you seem to want is not anonymizing, but rather just From: address munging plus perhaps putting the original From: address in Reply-To: in order to accommodate your specific network configuration. Aside from the fact that I am skeptical that this will accomplish your goal, this is not something that anyone else is asking for. Others have asked for the ability to mung the From: address while preserving the identity but not the email address of the poster, but these requests are generally motivated by a desire to prevent replies going to the poster, which is apparently not what you want. I suggest you figure out exactly what criteria these private network servers are using to reject mail, and if it is in fact based on the From: address, you try to convince the admins of these servers that making accept/reject decisions based on something so easily and often spoofed in spam as the From: address is not an effective anti-spam measure. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
