remote_smtp defer (-44)

[adapter]

hi,

i have a problem with my smtp, if i send email btw my 2 server i can't receive it, checking the log i have the following error:

T=remote_smtp defer (-44): SMTP error from remote mail server after RCPT
TO:<[email protected]>: host domain[ip]: 451 Could not complete
sender verify callout


what's wrong?

As it says, sender verify callout failed. Try disabling that option in WHM > Exim configuration Editor

Does this cause any other issues or possible security risk with spam when this is disabled?

It's not a security risk, but could well increase the amount of deliverable spam.
