mail notification triggering WF

[Almeida Viraj]

Hello friends,
    I want to trigger a workflow as soon as a mail arrives in my SAP inbox.
SAPConnect is configured for MS-Exchange server and
   I receive mails from outside R/3.
 
    Should task keep listenin to a event..say "Mail Arrived" ? or Inbound
Distribution (SO28) is other way ?
    SO28 is not much clear to me and I got the impression that i must have
SAPForm in place, submittin which a mail will come to
    SAPOffice and that will start Task...is this correct?
 
Please enlighten me upon this!
Thanks in Advance.
 
Viraj.
