Hi All,
We have a DKIM setup on Postfix Mail relay server and all DNS records SPF, TXT,A ,PTR are all properly setup.
We now have issue in DKIM verification by email wherein the mail with "Content-Transfer-Encoding: quoted-printable" in the header passess and the one with "Content-Transfer-Encoding: 7 bit" fails.
Any help on this?
Any suggestions on this ?
