[horde] No longer can access horde after upgrade

[Louis-Philippe Allard]

Hello,

I upgraded horde after recommendations from Horde's devs and  now I
can no longer access my portal.  I changed the settings in
imp/config/backends.php to use Gmail's imap & smtp servers,  it used
to work but now I try and I get:

Error when communicating with the mail server.

the horde log has this in it:

2011-05-04T20:46:54-04:00 ERR: HORDE [imp] IMAP read error or IMAP

Gmail's imap settigs are:

imap.gmail.com
Use SSL: Yes
Port: 993

smtp:
smtp.gmail.com (use authentication)
Use Authentication: Yes
Use STARTTLS: Yes (some clients call this SSL)
Port: 465 or 587

I tried smtp with both 465 & 587...

Anybody has a clue????
