LMTP error: Too many concurrent deliveries for user (in reply to end of DATA command)
I updated dovecot today and all over a sudden I'm getting:
Mar 6 14:40:46 mail postfix/lmtp[3150]: 3kz95y3nX3zCtTS: to=recipient@backup.invalid, relay=127.0.0.1[private/dovecot-lmtp], delay=88, delays=87/0.94/0.01/0.01, dsn=4.3.0, status=deferred (host 127.0.0.1[private/dovecot-lmtp] said: 451 4.3.0 recipient@backup.invalid Too many concurrent deliveries for user (in reply to end of DATA command))
Why is that? Which setting must I tweak?

Found the issue:
# doveconf |grep concurr lmtp_user_concurrency_limit = 0
-> not working
# doveconf |grep concurr lmtp_user_concurrency_limit = 10000
-> working again!
I guess 0 should disable the limit. It doesn't (anymore).

lmtp_destination_concurrency_limit on postfix side
lmtp_destination_concurrency_limit = $default_destination_concurrency_limit
postconf -d default_destination_concurrency_limit default_destination_concurrency_limit = 20
don't overload your storage by a high busy queue combined with to much parallel delivery to the mailstorage - thins don't get really faster that way

It's not a postfix issue. postfix is merely reporting what Dovecot said.

i know that on my own since i can read maillogs :-) anyways, we even use a lmtp concurrency level of 1 since years
