A friend is trying to send an e-mail from his Frontier.net e-mail address to an Optonline e-mail address.
He has no problems sending the e-mail if he uses the Yahoo Webmail interface.
His e-mail is bounced if he tries to send the e-mail directly from the e-mail software installed on his Windows 10 computer.
Looking up the IP address assigned by Frontier to his DSL modem/router I see his IP address is blacklisted by spfbl.net
"This IP was flagged due to misconfiguration of the e-mail service or the suspicion that there is no MTA at it."
I suggested he power off the router for a half hour, plug it back in and hope Frontier assigns him a different IP address.
He did as I suggested, was assigned a different IP address, tried to send the e-mail and received the same bounce message.
Frontier Help Desk seems to be clueless on this..
Any suggestions appreciated.
Steve
