for smtp mailservers admins
Configure the bcc addresses we provided you
to automatically duplicate each outgoing email.
Some Postfix and Sendmail «milters» can do it,
like mimedefang and milter-bcc.
Alternatively doublebackup is already integrated with:
RealSender - smtp servers with dedicated ip only.
Onboarding requires two easy steps:
ensure that your mailserver smtp settings are the ones provided by RealSender
tell us which RealSender authorized senders you want to archive
