[imp] Mail to Hotmail are discarded

[Manilal K M]

Hello all,
   I am having an unusual problem. When I send a mail from IMP to a
hotmail account, the mails are silently discarded. It's not displayed
either in Inbox or Junk mail folders. When I tried to send mail from
Ximian Evolution(Mail client) using the same mail server (POP/SMTP),
it succeeded. Did anybody faced this issue? Any hints to debug?

regards
Manilal
