Hi,
I am currently making a fresh install of email server. I am having some issue with dovecot-antispam (cf. other emails), and noticed that I was having issues on aliases, which apparently where not forwarded to the actual SMTP server after passing through dspam. Still don't figure why but temporarily disable the dspam filter, which anyway is not useful in the current state of this installation. Now the email to an alias are well forwarded to the real finale server. But I still have many emails which were deferred in the last days and I cannot have them decrease.
# ls -l /var/spool/postfix/defer/* | wc -l 297
If I run "postqueue -f" to flush this all, I can see the number down, but fastly comes back to 297. Reading the logs, they are passed to dovecot, which was probably the issue before I disabled dspam. It was trying to deliver a message after filtering it, but in the case of aliases, of course, it cannot because the account is not local (so it does not find the account and defers the email forever)! So it should give it back to postfix so that this one contacts the aliased server (gmail.com in the example below).
Feb 4 13:33:18 ks34186 postfix/lmtp[31100]: 82769869FA: to=< someemail@gmail.com>, orig to=someemail@mydomain.tld, relay=mail.mydomain.tld[/var/run/dspam/dspam.sock] conn use=28, delay=142296, delays=142277/19/0/0.41, dsn=4.3.0, status=deferred (host mail.mydomain.tld[/var/run/dspam/dspam.sock] said: 421 4.3.0 someemail@gmail.com Auto-Whitelisted (in reply to end of DATA command)) Feb 4 13:33:18 ks34186 dovecot: auth(default): master in: USER 1 someemail@gmail.com service=deliver Feb 4 13:33:18 ks34186 dovecot: auth(default): passwd(someemail@gmail.com): lookup Feb 4 13:33:18 ks34186 dovecot: auth(default): passwd(someemail@gmail.com): unknown user Feb 4 13:33:18 ks34186 dovecot: auth-worker(default): sql( someemail@gmail.com): SELECT maildir as home, 1004 as uid, 1004 as gid FROM mailbox WHERE username = 'someemail@gmail.com' AND active = '1' Feb 4 13:33:18 ks34186 dovecot: auth-worker(default): sql( someemail@gmail.com): Unknown user Feb 4 13:33:18 ks34186 dovecot: auth(default): master out: NOTFOUND 1
So is there a way please to flush this whole spool so that it now uses the new method (which is stop using dspam until I figure how to use it) and so that I can forward these emails to their recipient? Thanks.

P.S.: this is maybe more a postfix issue than a dovecot issue though... but you probably all know well postfix as well.
