sendmail/php mail() function problem

[Anon]

I made a PHP web site that sends out e-mails for various things, such as if you sign up for an account or if someone replies to a post you made on the site's message boards. The problem is that some mail servers attempt to validate the servername of the sender before they will accept the mail. How do I make it so that it puts my real domain (halfempty.dyndns.org) on outgoing e-mails instead of the name of the local machine (marlowe).

The error I get looks like this:
Diagnostic-Code: SMTP; 553 5.1.8 <apache@marlowe>... Domain of sender address apache@marlowe does not exist

The transcript looks like this:
... while talking to *** [stars added by me to conceal the identity of the offending mail server].:

MAIL From:<apache@marlowe>
<<< 553 5.1.8 <apache@marlowe>... Domain of sender address apache@marlowe does not exist
501 5.6.0 Data format error

Any & all help is appriciated.

Well... One sollution I can think of is in your php.ini file you could put the following:

sendmail_path = -t -i -f [e-mail]

I think that would work but dont qoute me on it. I usually just do it there hard way and do popen() to the sendmail script and send it manually.

The -f option gives sendmail the name of were its coming from.

Hope that helps!

Yep, that seems to do the trick. Thanks!

In the end, the mail gets sent fine, but sendmail takes a long time to send the mail, even when I tried using it from the command line. In the log, there will this

-Dec 5 19:07:38 marlowe sendmail[2126]: My unqualified host name (marlowe) unknown; sleeping for retry
-Dec 5 19:08:38 marlowe sendmail[2126]: unable to qualify my own domain name (marlowe) -- using short name

which basically means that it can't figure out its domain name, so it sleeps for a minute, then comes back and manages to send the mail anyway.

Obviously, I want to get rid of this one-minute delay. I know this isn't really even a PHP question, but I was wondering if anyone knew how to fix this sort of thing.

I just stumbled upon this because I was having a problem with sendmail being very slow myself. I fixed my problem by editing /etc/hosts and making sure that the host name was on the 127.0.0.1 line. Anyway, you might give that a try if you haven't fixed it already.

Cheers.

Actually, I fixed mine the same way 🙂
