It is not necessary tho its not a bad idea. Your sendmail is merely acting as a client to your ISP's sendmail - so as long as your ISP sendmail is happy (on correct net, authorized etc) all is fine. > One problem with such simple masquerading is when you send out a mail > using a local LAN address, it fakes your local domain to be the ISP's > domain, and that constructed address happens to be the same address as > someone else on your ISP. That is -not- correct. The outside world will see the ISP sendmail outbound MX and it will have a unique and reversable IP. The internal IP may show up in a received line and plays zero roll at all. It is not a problem in any way. gene -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
