Resolved Local SPF rule breaks SPF check

[Kaspar]

When I set any local SPF rule include with the argument type "include" the SPF check for incoming email seems to break. Resulting in an Error code: (31) include: or redirect= caused unlimited recursion message in /var/log/maillog.

Other 'argument types' in the local rule do not seem the cause any problem, such as a: or mx:. But Any local rule that has the include argument type causes an error. For example include:spf.antispamcloud.com or include:_spf.google.com. Any one else able to reproduce this? Is this expected behavior?

Hey, i know its an old Thread but maybe for other persons:

• Use the current entry from Hornet include:spf.hornetsecurity.com
• In another case, it was due to another provider's SPF record. It wasn't RFC compliant.

Use the current entry from Hornet include:spf.hornetsecurity.com

Why? What does that solve?

The issue described above was a bug know PPPM-12075 and fixed in Plesk 18.0.31.
