Consolidating mozilla/Netscape Email

[Tom Parquette]

Hi!  I don't subscribe to ports.  Please CC me on any replies.
I'm also not sure if this should be here or on questions...

I normally use mozilla (V1.4) for my MUA.
I also have some Netscape (various releases) Email files saved but I do 
not have Netscape installed.

I would like to consolidate multiple Netscape and mozilla Email files 
into the mozilla "folders" that I'm using now.
I had to change the ID I normally use so samba would be happier.  (Samba 
did not seem to like mixed case user IDs.)

I've looked at the mozilla help and I think I can figure out exporting 
my address books as ldif files and importing them into the new address 
book.  I have not found/figured out the stored passwords file yet.

My bookmarks appear to be a case of manually merging the bookmarks.html 
files

Nothing I have found in the mozilla help or searching the net seems to 
explain how to export/import and/or merge the various MUA "folders" and 
the Email messages they contain into the new Email instance.  (Please 
excuse the terms.  I'm not sure what some of the appropriate terms are.)

The only hits I seem to find talk about migrating to M$ Outlook.
This is a 5.1-CURRENT (not quite up to the bleeding edge) with mozilla 
V1.4 installed.

Any ideas would be appreciated.
TIA...
