Hi Guys, right now , we have some user cannot send the mail out from the php , and i set the "sendmail_from = email@example.com" , will it be ok? The things i want is for them to send the email and the address that sent out is their , not ours. do i have to tick this option in WHM? "Prevent the user 'nobody' from sending out mail to remote addresses (php and cgi scripts generally run as nobody if you are not using phpsuexec and suexec respectively.)" And some user said that , the sending mail scripts is working fine till last 2-3 days and they changed nothing , so do us , is there anyone seeing this problem before? Please advise.
