Symptoms
When I try to change my password within webmail, I have this error on top of page:Warning: fsockopen(): unable to connect to localhost:106 in
/home/httpd/vhosts/webmail/horde/passwd/lib/Driver/poppassd.php on line 34
Failure in changing password : Connection refused
Resolution
Make sure that xinetd/inetd server is running and 'poppassd' service is enabled in it. See /etc/xinetd.d/poppassd_psa for xinetd and /etc/inetd.conf for inetd.Also, make sure that 106 (poppasswd) port is open for localhost. Try to telnet to localhost to this port or run the following command on the server:
nmap localhost -p106
Starting nmap V. 3.00 ( www.insecure.org/nmap/ )
Interesting ports on localhost (127.0.0.1):
