Email Backup

Hello, How can i back up postfix email server to cimply with regulations?

Best regards

Setup archiving, you can use postfix's built in bcc to send each and every email to a script that then encrypts and stores it to file.

 

thx, is this incremental back up or simply backup what is on the server at that time.?

 

any update with this

thx

 

each and every single email that passes through the system will be stored.

 

is any application than can do this?

 

any suggestion on this?

 

i just use a cron job to do a
cp -a /var/spool/mail /home/backup/mail

 

Okay using my method here is a tip on how you can get it working

Create a script /etc/postfix/mail-backup.sh

Code:

#!/bin/bash

cat >> /backup_dir/mail-backup

Now for the always bcc use an address like email-backup
In your aliases file have a pointer to the script

Code:

email-backup: "|/etc/postfix/mail-backup.sh"

All the bcc'ed mail will be stored in the spool file /backup_dir/mail-backup.

NOTE that you can get more fancy with this and split the spool files if you have multiple users by reading the mail headers and getting the to address then store the mail in that users spool file.

Anyway this is just a skeleton for you to build on, haven't got the time on my hands to create you the full solution.

 

Restore

That solution framework looks pretty simple yet effective.. how would you restore from that in the event of total server disaster? let's assume that a seperate program copied the target file to a remote server and is completely intact.

 

In event of total disaster if you separated users to each have their own backup you can just copy back the file to their spool file if they are using mbox format if they are using maildir you will have to use a convertor to restore the mail.

The mails are stored in mbox format you if you want to restore a single email you can just use

Code:

mutt -f /path/to/file

to replay the single mail
