IMAP Error: Could not connect to localhost at port 143: Permission denied

[moogoogaipan]

Error log:

IMAP Error: Could not connect to localhost at port 143: Permission denied in on line 0

I am not sure what's causing this. I fired up iptraf and see if there is any traffic sending to 143 port on the localhost (tried remote host too) but seeing nothing. Looks like it doesn't even want to look for my IMAP server.

I even chmod 777 for logs and temp directories

Apache is a default setting for FC5. I yumed pear, imap support for php. Login via Thunderbird to IMAP server is fine.

Any help is appreciated. Thanks.

What I posted was the error logs from RC:

the telnetting to the imap server *looks* ok, but i'd start with a bit more testing there.

for the syntax of what to do after you've telnetted to localhost 143, take a look here:

http://www.macgeekery.com/tips/troubleshooting/troubleshooting_imap

1 LOGIN username password

should give you

1 OK Logged in.

does it?

I figured that SELINUX messed it up. Disabled it and it's OK now. Thanks for all the inputs.

Error log:

IMAP Error: Could not connect to localhost at port 143: Permission denied in on line 0

I got this after a 'yum update'. I tried "everything" , but still the same.

After on my knees begging the server to work (it did not help), I remember that I use modsecurity, and after checking the logs I see modsecurity_crs_30_http_policy.conf has seen the login script.

Not strange yet... I excluded modsecurity_crs_30_http_policy.conf in mod_security.conf and restarted httpd -> It works again. And I'm happy

Then I wanted to know what in modsecurity_crs_30_http_policy.conf stopped the login so I made a new blank modsec_auidit.log file and included modsecurity_crs_30_http_policy.conf in mod_security.conf again and then restarted httpd -> Now I wanted a fresh log in modsec_auidit.log... But the login still works... Now it's strange, but it works... But I'm still happy

Maybe this helps somebody...

Extra info, if you like, from modsec_auidit.log after last login
