as my vpn is either very slow or frequently fails, i tried the following:
changed ports 993,25 to 9993,2525 and then tried forwarding the new ports using ssh -L option to my corporate proxy. but when i clicked on 'Validate&Save', it fails with an error:
service.FAILURE: system failure: Unable to connect to IMAP server: DataSource: { id=d0b13b87-f4a2-4713-83d1-b6ae734f581e, type=imap, isEnabled=true, name=corporate, host=localhost, port=9993, connectionType=ssl, username=balusss, folderId=1 }

what i want is to access my corporate mail, without vpn.

can some one help me?
