Archiving Emails from a Qmail Based Email Server
Qmail has the ability to set up a mailbox where all emails that Qmail handles get copied to. Here is an adapted version of the appropriate "Life with Qmail FAQ" article
QUEUE_EXTRA is a compile-time configuration variable that specifies an additional recipient that will be added to every delivery. This is used primarily for logging. E.g., the FAQ describes how to use QUEUE_EXTRA to keep copies of all incoming and outgoing messages.
To use QUEUE_EXTRA, edit extra.h specifying the additional recipient in the format "Trecipient\0", and the length of the QUEUE_EXTRA string in QUEUE_EXTRALEN (the "\0" counts as one character). For example:
#define QUEUE_EXTRA "Tmailarchive\0" #define QUEUE_EXTRALEN 13
Shut down qmail if it's running. If you installed the qmailctl script from the Installation section, that can be done by:
If you don't have the qmailctl script, you should use your startup/shutdown script or send qmail-send a TERM signal.
Then rebuild qmail using:
make setup check
prepare mailarchive user
Populate ~alias/.qmail-mailarchive with:
Finally, restart qmail.
