POP to mbox converter?

[Erik P. Olsen]

I am in the process of converting from OS/2 to Linux and I have thousands of
e-mails saved in separate pop files. Does anybody know of a program that can
convert all these pop files into mbox files? Or if I would have to it myself
what is the precise structure of those mboxes?

What is a POP file? Sound like a Maildir format to me unless you saved 
each individual mail to file.

Anyways, try maildir2mbox

Hi Eric,

For starters if you have thousands of emails you probably do not want to use
mbox. mbox stores all emails in one file so storing them in a maildir format
is better.

What I normally do to convert emails from MS Windows is to create a new
account on my IMAP server and simply drag & drop them in the email client
program normaly Outlook Express or Outlook 2000

Fedora comes with dovecot which I have not used and FC2 also has Cyrus
(Which I use on RH9) but it should make the conversion pretty simple.

If the files are stored in maildir format , dovecot can handle them 
easily .. no need to convert them to mbox...
Now john , this is a interesting idea.. the problem is that this 
approach is not very scalable... If you have a few users , then it's 
simple.. but if your network has hundreds of users, then it'll be a 
daunting task...
I wonder if there is a easier way to do this kind of migration....

Yes that's correct, but Erik's email is in the singular and not talking
about a network with hundreds of users.

For 1 user probably not, for a network of 100's of course there is find,
write, modify a conversion script.

I've done both.

Hi John,

I did find out about the mbox structure and I have actually already
converted the emails. Not that I like the large mbox files but it turned
out to be very easy to write a script to do it. It was more important
for me to get on to Linux now than to wait for a more appropriate (and
possibly difficult) conversion. Now I have amble time to find out how to
convert from mbox to whatever is best. Is there a mail agent that would
archive the messages in an sql data base or similar?

BTW, thanks to all who have contributed with ideas for this conversion.

Eric,

I would suggest dbmail (dbmail.org). I use it to store about 700MB of email
in a mysql database. postgresql is supported also.

Look for the program 'raw-convertor' to convert mailboxes to dbmail sql.
