An RT question about carriage return

To all,

WE have many users that like to create their own tickets from email 

they get from their users (requestors). That way they can copy the part
of the email that makes sense and leave out all the redundant verbage,
etc. The problem lies in the fact that when they copy & paste the
portion of the email body they want (whaich may be a couple paragraphs),
the content gets slammed together with no line delimiters or carriage
returns in any field they put it in, whether it be a Custom Field,
Comment, or whatever. Any way to correct this? Thanks.
