IMAP backup script based in imapgrab

Backup remote IMAP server

After spending some time looking for a simple and reliable solution to backup a whole IMAP server, I have created this script to automate it from a comma separated files.

This script backup the whole messages and folders and returns a compressed file named as the user account [e-mail], also including a log of the backup

Table of contents

• Previous requirements
• Comma separated data source
• Customize server details
• References

Previous requirements

• python 2.3.3 or later
• getmail

If you are running an Ubuntu/Debian system you can install this running:

$ sudo apt-get install python getmail4

Move to a work directory, clone this repository and change execution permission of the files

$ sudo chmod +x imapgrab.py run.sh

To test the connection with the server and list the folders for an account can do this

$ ./imapgrab.py -l -s server.domain.com -S -p 993  -u username -p password

Comma separated data source

The file with the account´s details must look like this.

[e-mail],password1
[e-mail],password2

Customize server details

In the line 20 of run.sh file we can customize some details

./imapgrab.py -d -v -M -f $email -s server.domain.com -p 143 -u $email -p $pass -m "_ALL_,-INBOX.Trash,-INBOX.Spam" -L manager >> $email/backup_report.log

mbox or maildir

-M for maildir (default)

-B for mailbox

Server name

server.domain.com this is the name of the server

Port and SSL

-p 143 connection port

-S -p 993 add -S before port in case of a SSL connection

Skip some folders

-m "_ALL_,-INBOX.Trash,-INBOX.Spam" copy all the folders except INBOX.Trash and INBOX.Spam

Alternative user needed

-L manager if you run this script as root you need an alternative user to run imapgrab, in this case i have create manager user
