Hi, Friend, I have a system with Fedora 2/Mailscanner/ClamAV/Postfix and this system is used for our mail gateway, I would like to ask help for the below two issues:
1. How can we import our Exchange mailbox accounts to the Postfix system so we can use those databse to filter spam/rubbish mails?

2. How can I backup the Fedora 2/Mailscanner/ClamAV/Postfix system, so if there is a disaster, I can recover it back since we are not afford to have the E-mail system down for a long time?
Appreciate any help from you and you can E-mail me: aguang.pan@aguangpan.ipchina.org.

Best Regards
Aguang

Here is an article that reviewed several backup programs for Linux. Maybe one of those would work for you.

Otherwise, you can do a Google search and find tutorials on how to write scripts that use the tar command to backup your system.

Thanks and I will read that article thoroughly. Will come back for what I find/how to do the backup.

Again, any specialist knows how to automatically synchronize the user data between Citrix and Postfix so we can use it for spam mail filters.

Thanks.
