Hi, I have successfully used mhn2mbox (http://www.albany.net/~anthonyw/mhonarc/mhn2mbox) with MHonArc v2.4.6 to convert archives back to mbox format. Thanks, Anthony, for this program! However, when I had upgraded to MHonArc v2.5.4, I noticed that the message separators in the pseudo mbox didn't include email addresses any longer.
The reason seems to be that mhn2mbox makes use of the subroutine "mhonarc::extract_email_address()", which in the latest MHonArc version is dependent on the variable $AddrExp (set in mhinit.pl) to work. I fixed it by adding mhonarc::get_resources(); right after "mhonarc::initialize();" in mhn2mbox. I call your attention to this, since there might be other, more important, shortcomings when using mhn2mbox with the latest MHonArc version. / Gunnar
