Hi there everyone, When using PHP to send using sendmail, what is the option name so that failed mails bounce back to the email account of the domain SENDING it? Currently failed mails return to nobody@local and that screws the server up - bearing in mind I have multiple domains and just 1 needs this, which is why i'd rather have it set in the PHp script than in the php.ini or some other way. Sorry if i've confused you LOL. Chris
