dovecot passdb driver=checkpassword as external script for block ip
Refer to
https://dovecot.org/pipermail/dovecot/2015-March/099971.html
https://wiki.dovecot.org/PasswordDatabase
I tried to repeat the same thing.
Set these passdb:
passdb {
args = /myscript.sh ip=%r
driver = checkpassword
result_failure = return-fail
result_success = continue
}
passdb {
args = /etc/dovecot/dovecot-sql.conf.ext ( my working auth method )
driver = sql

Panic/Assert dns-lookup.c
Hi,
currently we deploying Dovecot as imap/pop3 proxy. Every few minutes some panic/assert occurred (we connect roughly 7k - 8k user at one imap proxy with a connection rate of 200/s).
We activate core dumps. Concerning the sensitive information in the dump we would prefer to not share the dump (e.g. i found our ssl private key in the dump).

Unable to see virtual users
I have a new Dovecot v2.2.9 installation and am having trouble
getting virtual users recognized.
Also, the example configuration listed on the Wiki generates config errors.
Note that I haven't tried running dovecot yet, I wanted to verify
that the config looked good first.
First, my configuration. I'm trying to use /etc/dovecot/users as my

Dear all,
I experience SegFaults in the imap binary on a LIST "" "" command,

Raw backtrace multiple passwords not allowed
Hi
Recently enabled support for encrypted passwords on my proxies -

Users with multiple password
Hi!
~ dovecot --version
2.2.22 (fe789d2)
I am wondering if there is a way to set up virtual users with multiple
valid passwords. We want to be able to provide users with
device/app-specific passwords for their email accounts, as well as being
able to create temporary "access tokens" for technical support when
required.
I quickly found out that passdb using passwd-file or an

Combining userdbs
Hi,
I think that using more than one userdb with setting the result
actions doesn't work as expected from the documentation.
The goal would be to set user-specific quotas for a few users with a
specific passwd-file like this :
cat /etc/dovecot/quotas
foo:x::::::userdb_quota_rule=*:storage=2G
The first userdb is passwd (with pam passwd):
userdb {
driver = passwd

Segfault with passwd as a second userdb at auth_fields_rollback
Hello,
I've been trying to set up dovecot to support passwd-file + passwd/PAM auth.
I made an unusual config (passwd-file as userdb failed to work for me), which
uses static as userdb:
===============
passdb {
driver = passwd-file
args = username_format=%u scheme=CRYPT /etc/dovecot/users
}
userdb {
driver = static
default_fields = uid=vmail gid=vmail home=/var/spool/mail/%d/%n

Disabling auth fallback to PAM
Hi folks,
According to the wiki,? it's considered a feature of Dovecot and its
ability to support multiple authentication sources that "if the
password doesn't match in the first database, it checks the next
one".

I think it's great that Dovecot allows auth sources to be stacked
like this, but I am not sold on the

Unexpected behavior with sieve_vacation_to_header_ignore_envelope = yes
Hello,
we face an issue with the vacation extension of pigeonhole. Our upstream
mail server (from which we pull our E-Mails with POP3) uses SPF and
performs a SRS re-write of the Return Path. Once the mail is processed
via our local postfix, it is delivered via dovecot deliver (using the
lda). When the recipient has a vacation rule enabled in sieve, the

LMTP doing passdb queries ?
Hi,
I can see dovecot is doing a passdb query when handling the LMTP RCPT
command.
That's kinda unexpected for me. I would have thought it only did a
userdb lookup.
I have disabled lmtp_proxy to be sure it didn't do a passdb lookup to
check the proxy field.
Is this expected? Doesn't the LDA only do userdb lookups?
