[imp] Error connecting to IMAP server. 22 : Invalid argument.

[Johan Huldtgren]

Trying to log into Imp(4.1.1) which I recently built on
a new machine, it results in the following error:

Error connecting to IMAP server. 22 : Invalid argument.

Although I get the above error I get "into" everything
else, eg I get the sidebar and can browse everything there
except mail.

Having dug around in all the log files and in some
mailinglist archives[1] it seems that IMP is incorrectly
trying to make a TLS connection instead of SSL.

 From maillog:

Jun  5 23:34:43 newmail dovecot: imap-login: Login: user=<johan>, 
method=LOGIN, rip=127.0.0.1, lip=127.0.0.1, TLS
Jun  5 23:34:43 newmail dovecot: IMAP(johan): Disconnected: Logged out

 From httpd-error.log:

[Mon Jun 05 23:34:43 2006] [error] [client x.x.x.x] PHP Warning:  
fsockopen(): no SSL support in this build in 
/path/to/my/horde/imp/lib/IMAP/Client.php on line 449, referer: 
https://newmail.mydomain.com/horde/imp/
[Mon Jun 05 23:34:43 2006] [error] [client x.x.x.x] PHP Warning:

/path/to/my/horde/imp/lib/IMAP/Client.php on line 449, referer: 
https://newmail.mydomain.com/horde/imp/

 From servers.php

$servers['imap'] = array(
    'name' => 'IMAP Server',
    'server' => 'localhost',
    'hordeauth' => false,
    'protocol' => 'imap/ssl/novalidate-cert',
    'port' => 993,
    'maildomain' => 'mydomain.com',
    'smtphost' => 'localhost',
    'smtpport' => 25,
    'realm' => '',
    'preferred' => '',
);

Running the IMP tests from test.php results in it
confirming the above information as correct and telling
me the amount of messages I have in my INBOX.

System Information:

FreeBSD 6.1-STABLE
postgresql 8.1.4
apache-2.2.2
php-4.4.2 (all required and recomended modules
are installed with the exception of memcached and mime_magic)
dovecot 1.0 beta8
horde 3.1.1
imp 4.1.1
ingo 1.1.1
nag 2.1
turba 2.1.1

This error is only appearing with Imp, reading mail via
thunderbird works flawlessly.

If anybody has any further information on what I can do to
solve this it would be greatly appreciated.
