Hi, I have a setup here where there are a bunch of boxes that host email for several domains. A shared email hosting basically. I want some insight on the pros and cons of
a. having a single whitelisted domain in the "d" tag of the signatures: All my outgoing mail (regardless of which domain it's from is signed with the same "d" tag) [email protected] d=whitelabel.mailserver.com [email protected] d=whitelabel.mailserver.com (simpler DNS TXT RR management?) vs. b. having emails signed with the corresponding "d" tags [email protected] d=pqr.org [email protected] d=xyz.net (helps if the pqr.org wants to migrate to a different email service provider?) Also, in case (a), would designating a separate "s" tag for each domain make a difference to my domain (whitelabel.mailserver.com) 's reputation with someone like Return-Path? I'm concerned about my subnet's reputation. There could be abusive domains hosted with me and I intend to take suspend it the moment I get the right feedback via the FBL.
