Dovecot authenticates vm-pop3d style virtual domains

assuming Maildir here

Requirements

create a configuration directory for passwords and aliases

mkdir -p /etc/virtual/nethence.com/

note email storage was covered over here.

create a few virtual user accounts e.g.

cd /etc/virtual/nethence.com/
imap_passwd pbraun PASSWORD-HERE >> /etc/virtual/nethence.com/passwd
cat /etc/virtual/nethence.com/passwd

Dovecot setup

see dovecot for a casual configuration example. here’s what specific for virtual domains

mail_location = maildir:/var/spool/virtual/%d/%n
mbox_very_dirty_syncs = yes
imap_client_workarounds = tb-extra-mailbox-sep tb-lsub-flags

passdb {
    driver = passwd-file
    args = scheme=SHA256-CRYPT username_format=%n /etc/virtual/%d/passwd
}

userdb {
    driver = static
    args = uid=vmail gid=vmail home=/var/spool/virtual/%d/%n
}

first_valid_uid = 500
last_valid_uid = 500

Troubleshooting

That didn’t work so well, we had to use Maildir instead

mail_location = mbox:/var/spool/virtual/%d/%n-home:INBOX:/var/spool/virtual/%d/%n

TODO

Not sure what this is for
