Hello,
I have a OpenBSD 7.5 with OpenSMTPD+rspamd+postgresql+dovecot setup with
virtuals (users and domains) and credentials in a postgresql database.
In addition to theses virtual users, i do some redirections to other
mail servers for specific aliases, and in that specific situation, i was
wondering if i could make opensmtpd completely bypass filters
(especially the rspamd filter).
Here is my smtpd config :
# This is the smtpd server system-wide configuration file.
# See smtpd.conf(5) for more information.
srs key REDACTED
srs key backup REDACTED
## Certs
pki gamindustri.fr cert "REDACTED"
pki gamindustri.fr key "REDACTED"
table domains postgres:/etc/mail/domains-pgsql.conf
table virtuals postgres:/etc/mail/virtuals-pgsql.conf
table passwd postgres:/etc/mail/passwd-pgsql.conf
table sympa file:/etc/mail/sympa.table
table sndrs postgres:/etc/mail/sndrs-pgsql.conf
table domains-max file:/etc/mail/domains-max.table
table addr-max file:/etc/mail/addr-max.table
