I initially installed Ubuntu 11.04 and used KMail for my email. All well and good.

Then I upgraded to Ubuntu 11.10. Presumably an upgrade of KMail took place as part of this. Now KMail won't even run; when I try, it tells me "Failed to fetch the resource collection" and crashes.

I don't mind switching to another email client, but I'd very much like to be able to recover all of the emails I have stored in KMail. Any suggestions on how to do this?

Thanks for any help anyone can provide.


Use this shell script for conversion of mdir to mbox format

#! /bin/sh
# Get a directory name as input and convert all mail files inside
# to mbox format
# NOTE: processing of subdirectories not yet implemented correctly:
#       all mails in subfolders are put into the same mbox
#       (it would be better if an mbox file will be generated for
#       each subfolder)
# History:
# Feb 06 2001 Joerg Reinhardt
# - first edition
# Feb 07 2001 Joerg Reinhardt
# - added usage output
# Feb 12 2001 Joerg Reinhardt
# - mails not containing a 'From:' field but an 'X-From-Line:' or a
#   'Reply-To:' field are now recognised and also processed (e.g. put into
#   the mbox file); this works fine for all my mails
# - added progress information
# - warning about corrupt files is now written to stderr
# Sep 8 2012 Kim Johansson
# - Time conversion to local timezone added
# - changed grep "Date:" to grep "Date: "

# check for argument or help argument respectively
if [[ ($1 == "") ||
($1 == "-h") ||

if [[ `find $dirname -type f` == "" ]]; then
        echo $dirname": directory empty."

If your mail is in mbox format it's easy

cd ~/.kde/share/apps/kmail/mail/
cat file1 file2 file3 ...  >>/var/spool/mail/$USER 

file1 file2 file3 ... , is your mail folders in mbox format (don't copy any .index .index.ids .index.sorted files)

Now you can get the mail from any mail client by choosing local delivery

I use thunderbird:
Server type: Unix Movemail
Server: localhost
This was done in Slackware, who uses sendmail as MDA, so your spool dir may be different.
