NYCPHP Meetup

[corey szopinski]

I¹m not a sendmail expert, and I¹d bet that something is screwy with either
my sendmail configuration or with our local DNS setup. I also agree that my
problem is outside of PHP.

For example when I try to do manually what PHP does with the mail()
function:

    sendmail -v corey at domanistudios.com <out.txt

(the ­v tag makes it verbose, and <out.txt pipes in a basic text file as a
body).

This takes just as long as mail(): about 30-45sec.

Mike DeWitt¹s trick doesn't seem to be working either, and I think it¹s
because of this line:

putenv("PHP_SENDMAILPARAMS= -O DeliveryMode=defer -f $fromaddress");

Does anyone know if ³PHP_SENDMAILPARAMS² is something special that sendmail
listens for? I¹m not familiar with how PHP, environment variables, and
sendmail cooperate with each other. Can anyone explain this? Do I need to
tell sendmail to look for this environment variable?

I¹m interested in how sites are able to send out millions of emails a day...
there must be a simple way that I¹m overlooking.
