Here is the message I get back from yahoo. It looks like the issue is in the from address, but I have the from address hard coded into the script and it works for every email address except yahoo accounts. Is there anything in the script that I need to change?
From Yahoo support :
relay=a.mx.mail.yahoo.com <http://a.mx.mail.yahoo.com> [22.214.171.124]:25,
delay=1.1, delays=0.34/0/0.23/0.54, dsn=5.0.0, status=bounced (host
a.mx.mail.yahoo.com <http://a.mx.mail.yahoo.com> [126.96.36.199] said: 501 Syntax error in parameters or
arguments (in reply to MAIL FROM command))
Is your form creating adding any special characters which Yahoo may be
Thanks for your help.
