<P><FONT SIZE="+1"><B><I>PURPOSE</I></B></FONT></P>
<P>The <B>procmail</B> command works under the hood to process mail, usually through the <B>.forward</B> file mechanism as soon as mail arrives. It can also be installed to work immediately through the mail program.</P>
<P>The <B>procmail</B> command sets some environment variables to default values, reads the mail message from <B>stdin</B> until an end-of-file marker appears, separates the body from the header, and then, if no command-line arguments are present, looks for a file named <B>$HOME/.procmailrc</B>. This file routes the message to the correct folder.</P>
<P>Arguments containing = are considered to be environment-variable assignments. Any other arguments are presumed to be <B>rcfile</B> paths.</P>
<P>This is a complex command that can cause some damage to mail processing if not configured properly. Check the online-manual pages for more detailed information about <B>procmail</B>.</P>

<TR>
<TD VALIGN="TOP"><B>-f</B>
<TD>Regenerates a leading <I>From</I> line with <I>fromwhom</I> as the sender (instead of <B>-f</B> one could use the alternate and obsolete <B>-r</B>). If <I>fromwhom</I> consists of a single -, then <B>procmail</B> will only update the timestamp on the <I>From</I> line.
<TR>
<TD><B>-m</B>

<TR>
<TD><B>-p</B>
<TD>Preserves the old environment.
<TR>
<TD VALIGN="TOP"><B>-t</B>
<TD>Makes <B>procmail</B> fail softly; if procmail cannot deliver to any a destination, the mail will not bounce, instead returning to the mail queue with another delivery attempt made in the future.
<TR>
<TD VALIGN="TOP"><B>-Y</B>
<TD>Works with Berkeley mailbox format, ignoring <I>Content-Length:</I> fields.

<P><B>readmsg</B> <I>option(s) selection folder</I></P>
<P><FONT SIZE="+1"><B><I>PURPOSE</I></B></FONT></P>
<P>The <B>readmsg</B> command extracts messages from a mail folder. You’ll usually do this when you’re preparing mail in a text editor and want to quote a specific, existing message from your mail folder.</P>
<P>You use the <I>selection</I> argument to specify which message to grab from your mail folder. A wildcard (<B>*</B>) means to pull all messages, while a number refers to a specific message (with <B>0</B> or <B>$</B> referring to the last message in the mailbox). In addition, you can pull messages that contain a specific string; these strings don’t need to be enclosed in quotes. In this instance, the first message that contains the string will be returned. (This method, by the way, is case sensitive).</P>
<P>You can also use <B>readmsg</B> from within the <B>elm</B> newsreader instead of an external editor, but it works a little differently in that situation. The mailbox used for retrieving messages is the current mailbox, not your inbox; the current <B>elm</B> message will be pulled; and the numbering scheme is a little different.</P>
