I would like to download all the e-mails in my old e-mail server. It uses POP3 and I'm interested in e-mails in "Inbox" and "Sent" folders. Once I have downloaded all the messages, I would like to make a script which lists all the e-mails between my e-mail address and one certain e-mail address in chronological fashion into single text file.

However, at first, I think I need to download all the messages to a single file with headers including dates and then create a sorting script. How to approach this?

I have used mailx in scripts for sending mails, but is it possible to use mailx to download all the mails from POP3 server into a single file?

    POP3 only supports an Inbox, with no additional folders on the server. (RFC 1939 Sec 8) Sep 30, 2013 at 5:02

Traditional mailx does not support IMAP or POP, but the one that comes with Linux does.

For your particular problem, I recommend using fetchmail instead. You can use the --mda option to have fetchmail execute a script of your choice for each downloaded message. It can even pass the From and To addresses as parameters to your script if you use %F and %T as placeholders in the command line.

First, create a mailsorter script:



case "$from-$to" in
  [email protected])
     echo "From $from  `date`" >> "$dest_mbox"
     cat >> "$dest_mbox"
     cat > /dev/null

Then run fetchmail -u myname popserver.example.com --mda './mailsorter /tmp/mbox %F %T'

While testing this solution, give fetchmail the --all and --keep flags to make sure that you don't delete your mail accidentally.

  • Thanks! Fetchmail was exactly what I was looking for. However, there is one problem- if I fetch all my e-mail over POP3, I still download only the ones I see in "Inbox" folder in web front-end. However, I would like to access e-mail in "Send" and "Deleted" folders as well. Is this possible?

    POP3 has no concept of any folder other than Inbox. Your Sent and Deleted folders probably reside locally on the client. Dec 2, 2013 at 23:55
  • 200_success, ok, I see. However, I have only used this e-mail account through web-interface. I found one way to access "Sent" and "Deleted" folders by coping e-mails from those folders to "Inbox". The other and more sane option would be probably to use IMAP if my web-mail provider supports it as IMAP should support other folders besides "Inbox"?

  • IMAP does support multiple folders. Use fetchmail --folder Sent (or fetchmail INBOX.Sent with some IMAP servers' folder layout). Dec 3, 2013 at 0:15
