No, it's you SPF data, published in a DNS TXT record (usually), that'sincorrect. At least that's what the other MTA claims.However, you've munged the useful data so there's nothing for any ofus here to check.Verify that the IP addresses you've authorized are really those thatbelong to the server that's sending the email for your domain.---Rich Matheisenge MVP--- Rich Matheisen MCSE+I, Exchange MVP

See Return codes were: 127.0.0.2 UCEPROTECTL2 UCEPROTECTL13.may be its caused this issue? how i can slove this issue? the emailrejection:550 5.7.1 SPF unauthorized mail is prohibited.SPF isn't a DNSBL.I checked and there's no PTR record for the IP address 7.11.50.25, noris that IP address found in any of the UCEPROTECT DNSBLs.I also checked DNS for your domain's MX record. The informationdoesn't seem to match what you say is in your SPF record!Non-authoritative answer:domain.com MX preference = 10, mail exchanger =sentry.domainbank.comsentry.domainbank.com internet address = 64.85.73.28The SPF record for domain.com looks like this:domain.com text = "v=spf1 mx ip4:69.63.211.0/25 ip4:64.85.73.0/25ip4:70.103.251.0/24 ip4:63.251.171.160/27 include:rnmk.com include:custhelp.com -all"When you're ready to reveal your domain name and the IP address youuse to send email, please post that information and someone will havea look at your situation. Until then, there's nothing anyone can doexcept to guess what your problem might be.and IP address as long as it's obvious to ahuman what the real data are.
