Unable to connect to Dovecot on localhost

[davidand36]

I have Dovecot running as my IMAP server on Ubuntu. I can telnet to it at localhost 143 and it seems to behave properly. But Roundcube reports this in the error log:

[18-Apr-2010 13:38:53] PHP Warning:  fsockopen() [function.fsockopen]: unable to connect to localhost:143 (Connection refused) in /usr/share/roundcube/program/lib/imap.inc on line 611
[18-Apr-2010 13:38:53 -0700] IMAP Error: Could not connect to localhost at port 143: Connection refused (POST /mail/?_task=&_action=login)

The only change I've made to the Roundcube configuration is this in main.inc.php:
$rcmail_config['default_host'] = 'localhost';

Your help would be greatly appreciated.
Thanks,
Dave

I'd start with /etc/hosts.allow and /etc/hosts/deny

For example hosts.allow may need something like:

Code: [Select]

dovecot:  127.0.0.1 : ALLOW

EDIT:  Also make sure 127.0.0.1  localhost is in your /etc/hosts file.

[davidand36]

/etc/hosts did have "127.0.0.1 localhost", and fiddling with /etc/hosts.allow didn't help. (On Ubuntu, Dovecot is launched through init.d, not inetd, by the way.)

As I mentioned, I can telnet just fine to localhost 143 and login and logout. However, I have determine that any php call of fsockopen("localhost",143,...) fails, so it's not specific to Roundcube.

I think you are beyond my skill level at this point.  It would however be helpful to know what version of php you are using.  Wouldn't hurt to include you php.ini file either.

Well, this is obviously beyond my skill level or I wouldn't be here. But there has to be an answer somewhere. My PHP details may indeed be helpful:

And my php.ini, which I don't believe I have touched, follows. (I used grep to eliminate comments and blank lines.). My thanks to anyone who can help.

In your php.ini I don't see any extension=xxxxx.so lines like I would expect too.  Although I con't think of any specific extension you would really need.

I also don't see the open_basedir = /path:/other_path; setting.  I would certainly expect to see your roundcube folder in the open_basedir path.
