Good day to all. It is necessary to duplicate outgoing and incoming letters from all mailboxes to a separate one, and arrange them in folders. All incoming emails are in the Inbox folder, and all outgoing emails are sent to the Sent Mail folder of the new mailbox.
Now I have done like this
always_bcc = relay@site.ru And all letters, whatever they may be, are placed in the Inbox.
Thank you in advance for your response.
