Truncating a mail file
Hi,
I have a Unix mail file that I need to truncate, based on the date of the messages. For those not familiar with the format, it is a single file for each user, with the first line of the mail message looking like the following:

From user@sitename.com Thu Apr 21 05:40:33 2011

Each succeeding message is separated by a blank line. I need to only keep 2 days worth of messages. What I would like to do is find the line for the first message from 2 days ago, and then delete all the lines in the mail file above this entry. Any ideas?

send-nntp

SEND-UUCP(8)						      System Manager's Manual						      SEND-UUCP(8)

NAME

       send-nntp, send-ihave - send Usenet articles to remote site

SYNOPSIS

       send-nntp [ -d ] sitename:hostname | sitename [ sitename:hostname | sitename ..	]

       send-ihave [ -d ] sitename:hostname | sitename [ sitename:hostname | sitename ..  ]

DESCRIPTION

       The send-* utilities are scripts that process the batch files written by innd(8) to send Usenet articles to a remote NNTP site.

       The sites to be fed may be specified by giving sitename hostname pairs on the command line.

       The sitename is the label the site has in the newsfeeds file, the hostname is the real hostname of the remote site, a FQDN (Fully Qualified
       Domain Name).  Normally, the sitename and the hostname are the same, and as such don't have to be specified as sitename:hostname pairs  but
       just as a sitename.

       send-nntp starts an innxmit to send the articles to the remote site.

       send-ihave  encapsulates  the articles in an ihave control message and uses inews to send the articles to a to.sitename pseudo-group. Using
       send-ihave is discouraged, nobody uses it anymore and even the author of this manpage is unsure as to how it  actually  works  or  used	to
       work.

       send-*  expect  that  the batchfile for a site is named <pathoutgoing in inn.conf>/sitename.  To prevent batchfile corruption, shlock(1) is
       used to ``lock'' these files.

OPTIONS

       -d     The ``-d'' flag causes nntpsend to send output to stdout rather than the log file <pathlog in inn.conf>/<program-name>.log.

NOTES

       You should probably not use send-nntp, but innfeed, or if that is not possible, nntpsend.

       The usual flags for a batch file for send-nntp are ``Tf,Wfm''.
