- Installed postfix to allow Xenforo to send emails. I'm using a email@example.com, which doesn't excist for postfix. I also don't have a postmaster@ abuse@ or whatever that is needed, since I'm very new to setting email services up. Are these actually required to prevent you from being blacklisted?
- Made sure that all my mail that is being sent from the dedicated server is DKIM signed. I verified this by using a website such as http://dkimcore.org/tools/dkimrecordcheck.html that does this for me by looking up the host record of a domain.
- Added an SPF record to my domain.
However my emails still are ending up in Gmail's spam. And according to LogWatch, postfix is having issues sending mail to Yahoo users. Does anyone here have experience setting up mail servers or preventing these kind of problems?
