php mail() very slow on centos 5.2 with postfix
I am running a centos 5.2 server with postfix and php 5 installed.
I am having problems with php mail(). Mails are sent but it takes about a minute for the page with the mail() function in it to load.
The mails are very short and text only. I had the same script on a different server before (shared hosting) were things just worked perfectly and very fast. I suspect that there is a problem with my server settings. Any ideas???
