cat <<ENDOFMESSAGE

Programs that access mail files often need to run set user id or set group
id so that they can create lock files in the spool directory, to prevent
other programs from updating the mailbox while af is doing so.

Af can be configured to use sub-programs to read and write folders, with the
sub-programs running with any required ids, or af itself can run with such
permissions, provided that no special user or group id is required, or that
your system has POSIX id controls; ie the ability to switch between the real
and effective ids as required.  If you need to run setuid root, then you
MUST use subprograms to read and write files.  Sub-programs have a slight
performance advantage on multiprocessor machines, while making af itself
read the files has performance advantages on other machines.

If in doubt take the default - it should work on any system.

As just mentioned, special permissions may be required to create lock files
in the spool directory.  If you need (and are able) to make af (or the
subprograms if you chose to use them) run with the required user and/or
group ids, and to make them run setuid or setgid, then you should type in
the name of the appropriate user and group as prompted.  Otherwise you
should just press return, and the executables will be installed with
ownership as for any file you create.

If you need af to run set user id or set group id to create lock files,
then you should give that requirement here.  A response of 'suid' means

set group id, and 'both' means both set user id and set group id.  If
you don't intend to use either set user id or set group id then just

Now we need to configure af for the Mail Transfer Agent (MTA) which you
are using.  This is the program called by af to deliver mail to the
correct addresses, whether locally or over a network.  The MTA is usually
one of submit, qmail-inject, sendmail, smail, or delivermail, (in roughly
descending order of likelihood if they are present), or possibly direct
SMTP via some remote host (if your system doesn't have a local main system).
As a last resort, /bin/rmail or /bin/mail may be used.  Note that even if
one of the above MTAs is present it may not be in use;  if you aren't sure
which MTA your system is using, then check before you answer.

The full path to the MTA is needed, not just the name of the program
(eg /usr/lib/sendmail, not just sendmail).  If you are not using a local
MTA, but want af to connect to a remote machine to send mail, enter SMTP
(in upper case) as your MTA.

First we'll check for certain likely MTAs...
