Hi,

I am using Postfix and Dovecot. I have set up backup_mailbox@domain.tld, which gets mail copies from user1@domain.tld user2@domain.tld user3@domain.tld, the copy option is set in postfix recipient_bcc_maps = path_to_file_recipient_bcc. In recipient_bcc file I have:

user1@domain.tld backup_mailbox@domain.tld user2@domain.tld backup_mailbox@domain.tld user3@domain.tld backup_mailbox@domain.tld

Postfix does the job and copies user1, user2, user3 emails to backup_mailbox. But I also want to filter mails in backup_mailbox and to put user1 mails to USER1 folder in backup_mailbox, user2 mails to USER2 folder in backup_mailbox and so on. How this is possible? I made an entry in subscriptions file of user1, user2, user3. Now I have folders .user1, .user2, user3 in backup_mailbox folder and I can also see these folders through webmail client (squirrelmail), but how do I put email copy which comes from user1@domain.tld to backup_mailbox@domain.tld to go not to main folder of backup_mailbox but to USER1 folder in backup_mailbox folder.

Thanks for any suggestions.
