Connected to localhost. Escape character is '^]'. * OK Dovecot ready. a login myemail@mydomain.com mypassword a OK Logged in. i have dovecot configured to listen only on localhost:143, but i changed that to *:143 and restarted dovecot just to make sure that wasn't the issue. the test.php returns no critical errors, and everything related to imap is installed and working properly. the phpinfo() also shows imap as installed/configured. here's my servers.php settings: $servers['imap'] = array( 'name' => 'IMAP Server', 'server' => 'localhost', // 'server' => 'fqdn.myhost.net', // 'server' => '127.0.0.1', 'hordeauth' => false, 'protocol' => 'imap/notls', 'port' => 143, ); note: i have tried to get this to work by changed out servers.php and using the loopback and/or the fqdn, but it doesn't really seem to make a difference. unless i specify 127.0.0.1 under authentication credentials screen, i cannot get into imp once i am inside imp, the only way i can get fetchmail to work is to specify 127.0.0.1 under server. if i put in localhost, i get the following message when i try to fetch mail: > Fetchmail: Cannot connect to the remote mail server: No such host as localhost let me know what additional info i can provide and/or what tests/config changes you would like me to make to assist in getting this working. thanks, -e Thu, 11 Feb 2010 21:42:20 +0000 https://bugs.horde.org/ticket/8869#t57967 This would inidicate a PHP and/or system issue, not an issue with Horde/IMP code (since we are reliant on PHP/system calls to do the name resolution for us).
