Why are you doing it this way? I'm just curious because in my small
mail server, I just have a definition in my master.cf which looks like
this:
# Updated to support + addressing, 20210402
spamass-dovecot unix - n n - - pipe
flags=DRhu user=mail:mail argv=/usr/bin/spamc -u debian-spamd -e
/usr/lib/dovecot/deliver -a ${rec
ipient} -d ${user}@${domain}
And in my main.cf I have:
virtual_transport = spamass-dovecot
The whole idea being that postfix uses the dovecot deliver tool to
insert mail into dovecot, which gets the right notifications workins.
It's not clear to me what mail tool you're using.
How is your 'dovecot' transport defined in the postfix master.cf file?
I'm honestly not going any replication, but I'm thinking that the
'pipe -n ...' stuff you're doing is the root cause here.
