Submission / Postfix / XCLIENT
Hi all,
while testing the new Dovecot Submission Proxy feature, which we greatly
appreciate and have been anticipating for a long time, some issues occured.
Dovecot is unable to submit mails via XCLIENT:
< XCLIENT ADDR=185.115.176.12PORT=39074
> 501 5.5.4 Bad ADDR syntax: 185.115.176.12PORT=39074
Postfix is unable to parse the XCLIENT command from Dovecot submission
proxy, as a space seems to be missing.
After checking the source code, the issue looks easy to fix - at least
to me as a...

Workaround for infinite loop in XCLIENT command bug
Hello,
I am running Dovecot 2.3.5 package on OpenBSD 6.5 and it looks like this bug which has been fixed in 2.3.6 is hitting me:
lib-smtp: client: Fix infinite loop in XCLIENT command interaction with server
https://github.com/dovecot/core/commit/5d03f39b345127b80d145ee90772739baa7ab810
so I was wondering if there is any workarounds? Maybe like disabling the XCLIENT command from the config file or something similar?
My original post regarding this issue is here:

Submission service, XCLIENT and HELO
...vecot's config is as follows (sanitized):
hostname = submission.domain.local submission_client_workarounds =
whitespace-before-path submission_relay_host = 192.168.1.1 <- postfix
submission_relay_port = 25 submission_relay_trusted = yes
Postfix is configured as follows:
smtpd_authorized_xclient_hosts = 192.168.1.2 <- submission server
Everything apparently works as expected, meaning that I can correctly
authenticate on the submission server and the email is relayed to
postfix, where I can see the original MUA's IP correctly logged.
There is, however, a little problem with the c...

Suggestions for dovecot-submission (XCLIENT NAME attribute)

Currently, Dovecot Submission doesn't forward NAME attribute when XCLIENT is enable:

Suggestion: Split login_trusted_networks
Hi,
For the upcoming 2.3 development, I'd like to re-suggest this:
It seems the use of login_trusted_networks is overloaded.
Example:
* It's used for indicating which hosts you trust to provide XCLIENT
remote IP's. (like a proxy)
* It's used for indicating from which hosts you trust logins enough to
disable auth penalty. (like in a webmail)
Often these two uses cases have a different set of hosts.
So you can't have one set of hosts which you trust for XCLIENT and
another set of h...

a-gnome-oyences
Most of my users are on kde, as am I (I really don't like gnome). I've got
one on gnome, though, CentOS 6.4, and I have a problem: I have to start an
agent running ->on login<-, so that the same one is in the environment of
every term window he opens. In kde, no problem, I modify
/etc/X11/xinit/xinitrc-common so that code in there calls our (newer)
ssh-agent instead of the stock one.

dovecot sasl with postfix: SASL LOGIN authentication failed: Connection lost to authentication server
...ton of errors of the form:
postfix/smtpd[7731]: warning: unknown[192.168.0.6]: SASL LOGIN
authentication failed: Connection lost to authentication server
Nothing is printed by dovecot in the logs regarding the error. It seems
that dovecot just hung up on postfix. (side note: no, can't use xclient
in nginx/postfix. But perhaps soon.)
After much digging I thought I solved it with:
login_trusted_networks = 172.20.20.0/24
mail_max_userip_connections = 0
This seems safe enough because dovecot is only providing sasl to
postfix, no connections to the outside world.
But the error is still h...
