There is multiple ways to implement this. When I did this long time ago I created separate userdb for protocol doveadm without quota restrictions and injected the overquota mail with doveadm command.

Yes but Memory is enough free. I had follow the link
It is very likely virtual memory (just address space, not actual memory)
that cannot be allocated. Dovecot restricts the amount of virtual
memory it can allocate ... something that most programs do not do. This
makes it possible to prevent a certain class of bug from using all the
memory. I think it defaults to 256M which would be 268435456 bytes.
Just a tiny bit less than the amount in the error message.
I think the setting in the link would only affect the replicator, not
all of dovecot. Your error does indicate it is the replicator that had
the problem, but I think setting the limit more globally would be
desirable. If I have the wrong idea here, can someone please let me know?
In my config, I set default_vsz_limit and one instance of vsz_limit to
1024M because I was running into a very similar error message. I could
probably remove the explicit vsz_limit setting because I set the
default, but I haven't tried it, and this config works:

Bypass quota check
Hi all,
I have the following quota configuration:
lmtp_rcpt_check_quota = no
mail_plugins = notify mail_log quota
quota = dict:User quota::file:%h/dovecot-quota
quota_exceeded_message = Quota exceeded
quota_rule2 = Trash:storage=+100M
quota_warning = storage=100%% quota-warning -q 100 -n %n -d %d -e
OverQuota
quota_warning2 = storage=80%% quota-warning -q 80 -n %n -d %d -e FillQuota
quota_warning3 = -storage=99%% quota-warning -q 99 -n %n -d %d -e InQuota
quota_full_tempfail = yes
service quota-warning {
executable = script /usr/local/dovecot/quotamanager.sh
unix_listener quota-warning {
mail_plugins = notify mail_log quota imap_quota imap_sieve
mail_plugins = notify mail_log quota sieve
and the quota_rule (per-user) is retrieved by a specific SQL query in my
userdb.
I'm wondering if there is a way to send an email to an account even if
it's in overquota?
In other words: is there a way to bypass (or skip) the quota check,
maybe setting a sort of ACL, for example if an email comes from a
specific ip address?
Thanks in advance

When new certificate is added, dovecot is reloaded (around 20 times a

Unfortunately it's known for ages that dovecot is not capable of

There were some ideas which were never implemented:
