Email rejection?

Getting this message for some of my site members, is this just something that the receiver needs to resolve?


Connected to 216.83.236.236 but sender was rejected.
Remote host said: 451 4.1.8 Possibly forged hostname for 66.98.176.60

My guess is the sender is using his own ISP’s SMTP server to send mail (many block port 25 to all servers but theirs as an anti-spam measure), and the recieving server is seeing

user@yourbox.com in the sender line but the mail is coming from smtp.hisisp.com and the recieving mail server sees this and it doesn’t jive and thinks it spam.

Take a look at this

Hope this helps, though not sure what you can do about it.
