we use OMP 3.3.0-7.
When OMP tries to send an Email to a gmail.com-Email-Adress, this Email was blocked from the recipient with
“…
----- The following addresses had permanent fatal errors ----- xxxxx@gmail.com (reason: 550-5.7.26 This message fails to pass SPF checks for an SPF record with a hard)
…”
Emails to other Email-provider are successful.
Have someone a tip/idea what we can do that also Emails to gmail are successfully sent?
