Hello,
The problem is same like for the hmail_autoresponder in the past. Check here:
Issue 19 - myroundcube - Autoresponder and MsSQL - Project Hosting on Google CodeSo in the "hmail_forwarding.php" I replaced the
"SELECT * FROM" on line 30 to
"SELECT accountlastlogontime, accountforwardenabled, accountforwardaddress, accountforwardkeeporiginal FROM"
Now it works just fine.
My platform is Windows Server 2003/MSSQL2008/PHP 5.2.11/FastCGI/RC 0.3.1
