.SH NAME
mailcompat \- provide SunOS compatibility for Solaris mailbox format
.SH DESCRIPTION
.LP
\fBmailcompat\fR is a program to provide SunOS 4.\fIx\fR compatibility for the
Solaris mailbox format. You would typically run  \fBmailcompat\fR to be able to
read mail on a workstation running SunOS 4.\fIx\fR when your mail server is
running Solaris.
.sp
.LP
Enabling \fBmailcompat\fR creates an entry in your  \fB\&.forward\fR file, if
it exists.  If this file does not exist, \fBmailcompat\fR will create it.
Disabling \fBmailcompat\fR will remove the entry from the \fB\&.forward\fR
file, and if this was the only entry, will remove the entire file.
.sp
.LP
To execute \fBmailcompat\fR, log onto the Solaris mail server and enter
\fBmailcompat\fR on the command line. Answer the queries provided by the
program.
.SH USAGE
