Error by attaching .PDF + fetchmail: MDA returned nonzero status 75

Hi There!
My RT 4.12 + Centos works fine and my fetchmail as well. But sometimes, just
for some PDF attachments I got an error " HTTP request failed: 500 Internal
Server Error. Your webserver logs may have more information or there may be
a network problem " by WEB UI or " fetchmail: MDA returned nonzero status 75
" by fetchmail. It’s happened no matter what the file size is.

I’ve checked some points:
Package mod_perl-2.0.4-11.el6_5.x86_64 already installed and latest version

There are no error on my logs, except on my fetchmail log file when I tried
to get the e-mail trough MDA, but it’s happened just for some PDF files. I
still have not identify which type of file format it is.

I’ve following this:
http://requesttracker.wikia.com/wiki/TroubleShooting#Syslog_error_.27MDA_ret
urned_nonzero_status_75.27_when_using_fetchmail.2C_procmail_or_similar

I’ve following this link: http://www.modssl.org/docs/2.8/ssl_faq.html#ToC49

In some forums, someone has indicated this:
/etc/request-tracker3.6/apache2-modperl2.conf
At the bottom it says:

Limit mail gateway access to localhost by default

<Location /rt/REST/1.0/NoAuth>
Order Allow,Deny
Allow from 127.0.0.1

But… I do not have this file!

Hello Everyone!
I’m again…:slight_smile:

The question is…there is no left space on /tmp!
[warn] [client my_ip] (28)No space left on device: mod_fcgid: can’t write
tmp file for stdin request, referer

The RT use /tmp to record something? Is there a way to change that?

Thank you.-----Original Message-----
