406 Not Acceptable

[kfordham281]

"Not Acceptable

An appropriate representation of the requested resource / could not be found on this server."

This happens when I try to send an email; pretty much only when replying. This happens a few times a day and I can't seem to find any pattern. I can reply to some messages fine, and others I get this error.

[flosoft]

hmm, what is your software is your mailserver and what is your Webserver? PHP Version etc.?

[kfordham281]

Mail software is Exim
Apache 1.3.34
php 4.4.2
mysql 4.1.19-standard

Hope that helps!

[flosoft]

Did you set the rights to 777 on logs and tmp?

[Prasad1337]

Remember for some hosts (like mine) 777 isnt accepted, so if 777 doesnt work , try CHMOD 755.

[neodg]

the mod_security (Apache) module blocks that

[kfordham281]

Yes, currently tmp and logs are both set to 777.

[flosoft]

hmm ... I'm out of ideas. Especially I don't really know a 406.

Whats in you error log? This may help...

I would likely say the PHP Fatal Error is the 406 error in question as it's often.

[SKaero]

Can you post your program/lib/imap.inc?
