.SH NAME
mailcompat \- provide SunOS compatibility for Solaris mailbox format
.SH DESCRIPTION
.sp
.LP
\fBmailcompat\fR is a program to provide SunOS 4.\fIx\fR compatability 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
.sp
.LP
See \fBlargefile\fR(5) for the description of the behavior of \fBmailcompat\fR when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).
.sp
.LP
Depending on the security settings in your system, \fBmailcompat\fR can fail to create a \fB\&.forward\fR file.  If you encounter such a failure, take the steps outlined below.
.sp
.LP
As root user or user with comparable privileges, enter:
.sp
.in +2
.nf
% \fBsendmail -bv $USER\fR
.fi
.in -2
.sp

.sp
.LP
You receive one of the following two messages. The string \fBfwtest\fR is for example purposes only.
.sp
.in +2
.nf
fwtest... deliverable: mailer local, user fwtest

"|/usr/bin/mailcompat fwtest"... deliverable: mailer prog,\e
user "|/usr/bin/mailcompat fwtest"
.fi
.in -2
.sp

.sp
.LP
The first message, with the \fBlocal\fR designation, indicates that \fBmailcompat\fR was not able to create the \fB\&.forward\fR file. The second message, with the \fBprog\fR designation, means that \fBmailcompat\fR succeeded in creating \fB\&.forward\fR.
.sp
.LP
As a further check, invoke:
.sp
.in +2
.nf
% \fBcheck-permissions $USER\fR
.fi
.in -2
.sp

.sp
.LP
You should get the message:
.sp
.in +2
.nf
No unsafe directories found.
.fi
.in -2
.sp

.sp
.LP
If you get a message different from this, it might indicate a reason for \fBmailcompat\fR failure. You should correct any conditions pointed out by the message before retrying \fBmailcompat\fR.
