Hi,

I have strange problem. When I want to use php mail function in script the mail function doesn't work.

I receive an error mail with:
Remote host said: 554 5.7.1 Spoofing Sender in Local Domain .

I have in maillog following error:
Aug 26 13:03:12 hosting plesk sendmail[19728]: handlers_stderr: SKIP
Aug 26 13:03:12 hosting plesk sendmail[19728]: SKIP during call 'check-quota' handler
Aug 26 13:03:12 hosting plesk sendmail[19730]: sendmail unsuccessfully finished with exitcode 100

The From field is all time blank.

Can anyone help me?
