[leglug-users] sendmail and apache issue with fedora

[Chady Kassouf]

Hi Abdallah,

It was finally resolved a couple of hours ago.

The syntax is correct, and what was baffling me was if I call the script
directly from a login:

$ perl test.cgi

it sends the mail. Even doing this:

$ sudo -u apache perl test.cgi

it also sent the mail, just hitting it form the webserver failed on closing
the pipe with sendmail.


Finally, after a gazillion combination of search queries, I was able to
pinpoint the reason of the issue.

can you say SELinux?

that was the reason nothing was showing up in the maillog, cause it was
being denied at the kernel level and not even reaching back.


Regards,
