mail - sendmail

Hi! I wanted to use the full SMTP-Protocol including "MAIL FROM:" and "RCPT TO:", and therefore I can't use mail(). I have written a perl-script, I call from PHP, that connects to the SMTP-server directly and this worked fine - until a server went down, and my ISP's-SMTP-Server told my perl-script, that the emailaddress is not routable. If the mail had been in a mailqueue, no problem - after a few hours it would be up again! So is there a way to combine these 2 features? 1. give the mail not directly to the SMTP-Server, but to the mailqueue 2. use the full SMTP-Protocol: for example: -- MAIL FROM: bounce@mydomain.com RCPT TO: recipient@someotherdomain.com From: Newsletter <webmaster@mydomain.com> To: Newsletter-List <newsletter-list@mydomain.com> Subject: blabla BODY ... -- thanks Michi -- Aufgepasst - jetzt viele 1&1 New WebHosting Pakete ohne Einrichtungsgebuehr + 1 Monat Grundgebuehrbefreiung! http://puretec.de/index.html?ac=OM.PU.PU003K00736T0492a
