php mail() sendmail hanging

[Thomas S. Crum]

Pardon me if this is off list, but any help would be appreciated.

When hitting php pages that use the mail() function, I get a 5 second hang
in the browser.  The mail is then being delivered fine.

Many of the same scripts that use this mail function ran fine with ½ sec. or
less delay on my old redhat box. I am not blaming FreeBSD, as I'm certain I
just don’t have them configured the same.

Any fixes to make it run quicker would be greatly appreciated. I've included
the sendmail.mc and php.ini files below.

Best,
 
Thomas S. Crum
