Hello all, Sorry for a non-postfix specific question.
I am running into an issue with a big SPF record I had been maintaining. I went ahead a broke it up using the include: mechanism, but am still trying to figure out the limit I did hit. For testing purposes, I send emails from this addr...@spf.255.cuaemail.org to gmail, yahoo.com, and outlook.com The SPF record for that domain is made up of 255 ip4 addresses, the last of which is my true client IP. Please check it out with dig. gmail and yahoo fail the SPF test. outlook passes. Using addr...@spf.101.cuaemail.org, gmail also passes. The SPF for this domain has 101 addresses. Using addr...@spf.63.cuaemail.org, yahoo also passes. So am concluding these vendors have these limits for the number of IPs in a single SPF record... would that be correct conclusion? anyone knows if this is documented by these vendors? I opened a case with Google and so far they have been insisting there is no such limit! Thank you so much. Mohamed.
