courier mail server problems

Ok Guys. I have a huge problem, that I need solved fast. 500 points will be awarded to the person with the correct answer.

Problem:
We have a php script installed on our apache/php web server that sends an email (courierd) to a local user on the system.
The script works when sending email outside of the localdomain (mydomain.com), but doesn't work when sending email to mydomain.com users.

This is what I'm receivng in the apache error_log every time I attempt to send an email.


sendmail: ERR: submitclient: EOF from submit.
sendmail: Unable to submit message.

This error occurs only if we send email to anyuser@mydomain.com
however if we send an email outisde the domain through our php mail script to user@hotmail.com or user@yahoo.com or any other domain outside the local servers domain it WORKS LIKE A CHAMP.

Example Script:

mail("user@mydomain.com","test","test");


Things tried:
- we already tried setting ever known mail header to man
- we tail -f the maillog and couldn't find any errors at the time of submitting our test php script
- we did find errors when tail -f the apache error log file (the error is above)

I think if we can track down this error

sendmail: ERR: submitclient: EOF from submit.
sendmail: Unable to submit message.

We should have an answer.

Thank you so much!

"localhost.com" is almost certainly wrong and should be just localhost.

Can you use 'mail -s subject local-addr@local-domain.tld' to send mail?

Yes, this works fine. It just fails to function through my php script (*listed above).

Okay... What version of sendmail are you using?

How would I find this out?

The path to sendmail is "/usr/lib/courier/bin/sendmail"

jlevieCommented:
My guess is that the PHP application is invoking /usr/sbin/sendmail, which may not the the copy of sendmail that Courier expects you to be using. Are /usr/sbin/sendmail and /usr/lib/courier/bin/sendmail different?

PHP INFO FILE:


sendmail_from me@localhost.com me@localhost.com
sendmail_path /usr/lib/courier/bin/sendmail -t -i  

PHP is pointing to the right path. Anything else I should look for?

Hi Jlevie,

I actually solved this issue, but will award you for your efforts.
The problem seemed to come from the sendmail error not sending apache a SIGHUP signal when it encountered an error.
I restarted apache and it worked great after that.


Thanks.
