Using fetchmail to Backup Gmail with FreeBSDWritten by Mark Sanborn: Mar 19, 2008
Getting fetchmail to work in Linux or FreeBSD has always been difficult for me. The SSL certificates always seem to be a pain to configure. It has been particularly difficult to get fetchmail with Gmail working on FreeBSD since there are no complete guides written for FreeBSD.
I found a guide for FreeBSD that was written in shorthand and had pieces left out. The guide also had a comment in it claming that the article was copied. The orginal guide was great but it was not particularly for FreeBSD so I still ran into some troubles. I would like to give credit to the original author however because without his guide I would not have been able to get this working. So thank you Charles Levert.
cd /usr/ports/mail/fetchmail/ make install clean
cd /usr/ports/security/ca-roots make install clean
cd /usr/src/crypto/openssl/certs wget -O Equifax_Secure_Certificate_Authority.pem https://www.geotrust.com/resources/root_certificates/certificates/Equifax_Secure_Certificate_Authority.cer openssl x509 -in Equifax_Secure_Certificate_Authority.pem -fingerprint -subject -issuer -serial -hash -noout /usr/src/crypto/openssl/tools/c_rehash .
For some reason I was getting a permission denied error when running this. If you get this you need to make c_rehash an executable. To do this use this command:
# chmod 755 /usr/src/crypto/openssl/tools/c_rehash
# file 594f1775.*
Add this to ~/.fetchmailrc. Replace the email@example.com with your email addres. Replace the password with password Replace ‘user’ with your local FreeBSD username
poll pop.gmail.com with proto POP3
user 'firstname.lastname@example.org' there with password 'xxxxxxxx' is user here
options keep ssl sslfingerprint '59:51:61:89:CD:DD:B2:35:94:BB:44:97:A0:39:D5:B4'
sslcertck sslcertpath /usr/share/ssl/certs
Run this command to give it a whirl.
$ fetchmail -d0 -v pop.gmail.com
If you get an error saying that there was a fingerprint key mismatch. Copy and paste the key in the error message into your ~/.fetchmailrc file replacing the key that is in there.
To protect this file from other users reading your Gmail password change the permissions.
$ chmod 600 ~/.fetchmailrc
Gmail only wants to be bothered once every 5 mintues (300 seconds). So use this command to start fetchmail in deamon mode with a poll of 300 seconds.
$ fetchmail -d 300
If you have your pop settings for Gmail set for all messages this will download them all to your local computer. If you have it set for new messages, only new messages will be downloaded.
