I'm running Mandrake 9.2, and using Postfix as my MTA.
Whenever I try sending email through my php script to an sbcglobal.net email, for example, it keeps getting bounced. I know many other people have had the same problem.
Apparently, it seems I need to relay messages to my ISP SMTP server in order for the messages to be sent successfully.
I get to the point where the messages are returning a "authentication required" message... so here's what I did, according tohttp://www.mandrakesecure.net/en/docs/postfix-sasl.php
Added the following to main.cf:
# Other configurable parameters
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = $myhostname
smtpd_recipient_restrictions = permit_mynetworks,
smtpd_sasl_security_options = noanonymous
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
Added the following to sasl_passwd:
assword (where destination is smtp.sbgglobal.yaho.com and username and passwd are my username and passwd for my sbcglobal account)
Next, I ran: 'postmap main.cf' and 'postmap sasl_passwd', and reloaded postfix.
Why are my messages still not being authenticated and sent successfully?
Any help would be greatly appreciated!
