I wonder, are there any issues, if an SPF a:host entry resolved to
multiple IP addresses?

smtp.imp.ch has address
smtp.imp.ch has address
smtp.imp.ch has address
smtp.imp.ch has IPv6 address 2001:4060:1:1001::13:198
smtp.imp.ch has IPv6 address 2001:4060:1:1001::13:196
smtp.imp.ch has IPv6 address 2001:4060:1:1001::13:197

Customer SPF entry:

"v=spf1 +a:smtp.imp.ch -all"

Now this is being rejected with and SPF fail pointing to (customer
domain scrubbed)


Which recommends exactly the SPF record that is set.

Could it be that the check the remote site uses only looks up one IP
instead of all of them?

Kind regards
