You could probably use sendmail's "-t" option, to resend to all recipients shown in the mail headers. Or, if there's just the one recipient, you can always just explicitly supply them as a command line argument.
If the saved mail message has the mbox-style one-line mail header, you'd want to strip that off first...
tail -n +2 mbox | sendmail -t
Check your man page, though, in case Solaris has some alternative form of sendmail command installed.
Also, sendmail may give some kind of warning if you use the "-t" option and you're not invoking this as a user it considers trusted (and that is configuration dependent).

I have a user ("username") which has some mail in /var/share/mail/username (this is Solaris). The mail should have been forwarded, but for some reason has not been. Can the mail in the file above be somehow resent (re-received?) by sendmail or some process now that the user has configured /export/home/username/.forward?
