Hello to all: I have been trying to integrate and to stand up dovecot, postfix, mailman3 and opendkim. I have been studying the following: - https://www.frontline.ro/en/blog/how-to-configure-opendkim-with-postfix-on-debian-12-bookworm - https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.html#postfix - https://www.linuxbabe.com/mail-server/build-email-server-from-scratch-debian-postfix-smtp - https://www.linuxbabe.com/mail-server/install-dovecot-imap-server-debian
This appears to be the best available coaching, but it would take me weeks to find the time to follow this post: - https://pieterhollander.nl/post/mailserver/ I was trying to place the Maildir outside my Debian 12 virtual machine for easier backup. The directory /Debian-12-dovecot-Maildir is setup as NFS share on my NAS. I can orchestrate a daily backup or an rclone of that to OneDrive or some other cloud target via my NAS. I have these errors: Apr 02 11:17:01 shackleton12 postfix/local[795238]: CA26A2D23: passing <mail...@systemdatabase.ca> to transport=lmtp Apr 02 11:17:01 shackleton12 postfix/local[795238]: warning: connect #1 to subsystem private/lmtp: Connection refused Apr 02 11:07:00 shackleton12 systemd[1]: Starting dovecot.service - Dovecot IMAP/POP3 email server...
