- Here is the FORTRAN program I have received from Dan Fox.
- I have not yet tried it this program myself, but some users have tried and they
- were happy :-)

- I just sent this to Francisco... It was how I converted all the VAX
- mail folders over to files that unix mail would understand. There were
- a few reported failures, but it handled all my mail folders properly.

- c program: mailfix
- c--------------------------------------------------------------
- c purpose: convert VAX mail to UNIX
- c--------------------------------------------------------------
- c version: 1.0 : 25 Oct 1989 : D N Fox : NORDA Code 323
- c--------------------------------------------------------------
- c procedure:
- c 1. On the VAX side, if you have any new mail, read it
- c and exit MAIL so that when you come back into MAIL,
- c you have no new messages.
- c 2. Select all messages using something like:
- c mail> select/since=01-jan-1900
- c 3. Save all these to a file:
- c mail> extract/all dua10:[scratch.you]vax.mail
- c 4. ftp this file to your Sun
- c 5. On the Sun side, run the 'mailfix' program:
- c cat vax.mail | mailfix > mbox_vax
- c 6. Now you can read 'mbox_vax' as a normal mailbox.
- c In Mailtool, you can enter this name on the file line
- c and click on the 'folder' button.
