I am providing this information because I found it useful. I was inspired by Iain Thompson of The Register (http://www.theregister.co.uk/Author/2395/) to retrieve and delete my 15+ years of email.
Disclaimer: Computers suck. Also, I could be a complete idiot. I’m just some rando blog on the internets. Do the following at your own risk and please don’t hurt me if something goes wrong.
Prepare Your Account
Disable Two-Step Verification
Enable “Allow apps that use less secure sign in”.
Remember to turn them back once email download is done. Then delete your Yahoo account anyway.
Need to have fetchmail and maildrop installed. I’m an Ubuntu user so I just did:
sudo apt install fetchmail maildrop
poll pop.mail.yahoo.com service 995 protocol POP3 user "email@example.com" ssl password "mypassword" fetchall mda "/usr/bin/maildrop"
Verify with ‘fetchmail -v -c’ (verbose and check). Should see a successful login to your Yahoo email.
NOTE: fetchmail’s default behavior over POP3 is to *DELETE* your email once retrieved. I’ve left this behavior in place. If that’s not what you want, consult the fetchmail man page.
Enable DEFAULT=”$HOME/Maildir” to push mail straight to my account instead of through a MDA.
Build a Maildir
From home directory, run
Will create the necessary Maildir tree. Use Maildir rather than mbox format because writing to a single file (mbox) is risky; could be corrupted in event of a crash. Maildir writes every email to a separate file.
Test Test Test!
Run fetchmail -v -B 1
Will fetch verbose ONE message for testing the configuration. Should see login and one message downloaded. (deep-thought is my hostname)
Here’s me after downloading three messages:
…deep-thought:~% find Maildir
Maildir Maildir/cur Maildir/new Maildir/new/1476108117.M788587P6060V0000000000000801I0000000002F42B11_0.deep-thought,S=34486 Maildir/new/1476107958.M23066P5120V0000000000000801I0000000002F42B10_0.deep-thought,S=49456 Maildir/new/1476107905.M287749P5102V0000000000000801I0000000002F42B0F_0.deep-thought,S=25386 Maildir/tmp
Release the Hounds.
Let’s go for it. Run
fetchmail -v | tee log.txt
|tee log.txt to save a log of the run in case anything goes wrong.
