how to read a file till it encounters a blank line

Hi ,
I want to read a file starting with "*" up to till it encounters a blank line and to redirect this output to a different file.Plz suggest how to write a script for this.

e.g:-

  • PK Sent Email (11.23)
    CALYPSO 1243215 9116457 NEW TRAD FAILED Nov 23 2007 9:34AM OASYS: DPS: SINGCORP invalid use of FirmA

  • PK sent email (11.20)
    CALYPSO 1238957 9088029 ONRUNDEL FAILED Nov 20 2007 8:04AM OASYS: Unable to find CUSTOMER account BS

Here I need to read from * until it encounters a blank line.
