    I tried to use alternate mail-sending method using SMTP PHP, I had an error below:

    Code:
    The following errors were outputted by PHP when attempting to send mail:
    
    Warning: 554 Unexpected response from SMTP server during TO address transmission in [path]/includes/class_mail.php on line 711
    Any clue what's wrong?

    ironically all of my mail clients are working fine when sending mail through the same SMTP (provided by ISP) so I think it's not my ISP's fault.

    Hello,not saying it's your ISP's fault but ISP's often have special routing for their own SMTP serveurs…

    Alot of ISP's will block outgoing port 25 and just open it to their smtp server and I've also seen specific routing problems on certain ports but only for short periods.
