SMTP error from remote mail server

Post by alan.m »

hello All,

When I try to send emails to one of my clients email address, I am getting below error on my webmail. Any idea why is that happening?

X=TLSv1.2:ECDHE-RSA-AES256-GCM-SHA344:256 CV=no: SMTP error from remote mail server after RCPT TO:<aaaa@xxxxx.com>: 550-SPF: x.x.x.x is not allowed to send mail from\n550 bbbb.com

it seems your SPF record has some issues, verify the mail sending IP and the IP mentioned in the SPF record, both will be different.
