pkg_add(1) has an environment variable PKG_PATH which should help with
what you want to do.  So what you'ld do is maintain a copy of the
default packages in, say:

    /repos/ftp.freebsd.org/.../packages/All

Then have your own package repository structures:

   /repos/mail-custom/.../packages/All/
                               .../mail/
                               etc.
   /repos/db-custom/.../packages/All
                            .../databases/
   /repos/web-custom/.../packages/All/
                              .../www/

(Actually, if I was doing this, and only had to support one OS version
and one system architecture, I'd probably dispense with all those
intermediate directories shown as '...' and just keep a nice shallow
directory tree).

Although I've shown other port category directories here, you're not
really interested in them: however, when you're building the packages,
say for a mail server, you can just set the PACKAGES environment
variable to /repos/mail-custom/.../packages and the package will be
automatically installed to the right directory -- but the extra
package category stuff will be created at the same time.

The copy of the package collection from ftp.freebsd.org needs no local
modification, so you could just setup an automated job to synchronise
your copy with the FTP server and download any updated packages --
with the permission of the administrators of the server you mirror
from, obviously.

Then on your mail server machines, just set:

    PKG_PATH=/repos/mail-custom/.../packages/All:/repos/ftp.freebsd.org/.../packages/All"

and similarly for the other classes of machines you're maintaining.

Now pkg_add(1) will search the current working directory, and then, in
order that list of directories on PKG_PATH to locate the package you
want to install.

	Cheers,
