Yahoo flagging mail as spam when using relay server
- by modulaaron
I'm using Postfix to relay mail from my site to my mail server. Mail is received properly at my Gmail and Hotmail accounts - only Yahoo is the problem. The Yahoo mail headers state:
Received-SPF: none
(mta1133.mail.mud.yahoo.com: domain of
[email protected] does not designate
permitted sender hosts)
In contrast, the Gmail headers state:
Received-SPF: pass (google.com: domain
of [email protected] designates
74.50.xxx.xxx as permitted sender) client-ip=74.50.xxx.xxx;
Reverse DNS is set up correctly, as is my SPF record.
Does anyone have any suggestions as to what I can do to solve the Yahoo problem (short of contacting Yahoo, as this is a brand new mail server)? FYI - I just set up domainkeys, but I'm not sure whether they should be on the origin or relay server.
Thanks
