Hi,
I've got serverA using smtp auth via serverB which is the Zimbra server.
User details are fine and I've setup my app to use same user auth and FROM field but I'm always getting the following error:
Code: Select all
zimbra1 postfix/smtps/smtpd[10242]: NOQUEUE: reject: RCPT from mydomain.com[my ip]: 553 5.7.1 <support@mydomain.com>: Sender address rejected: not owned b
y user clientportal@mydomain.com; from=<support@mydomain.com> to=<mygmail@gmail.com> proto
=ESMTP helo=<mydomain.com>
I'm using latest stable Zimbra.
Any help is much appreciated.

Your own code shows the auth user is
clientportal@mydomain.com, while the From is
support@mydomain.com. Those do not appear to match to me.

clientportal@mydomain.com is this address a distribution list or an alias ?

In my case it is a regular email address. I can send mails from webmail client, but from Outlook I will receive that error message

Regular webmail address does not mean your address supply in the from field is own by the user address used with SMTP authentication.

I have fix my problem for now by removing "reject_sender_login_mismatch" from "/opt/zimbra/conf/zmconfigd/smtpd_sender_restrictions.cf"

zmcontrol -v
Release 8.7.11.GA.1854.UBUNTU16.64 UBUNTU16_64 FOSS edition.
I have a development enviroment to move the configs to production but i am getting a problem on second step:
1st step) Setting a split domain:
https://wiki.zimbra.com/wiki/Split_Domain
No problem in this step, all working fine.
2nd step) For avoiding a user's password compromised to relay emails using a different email address than the one uses to authenticate with smtp:
https://wiki.zimbra.com/wiki/Enforcing_ ... ername_8.5
Then I got following error:
Dec 6 13:02:27 mail1 postfix/smtpd[48259]: NOQUEUE: filter: RCPT from mail1.test.tt[x.x.x.x]: <
admin@mail1.test.tt>: Sender address triggers FILTER smtp-amavis:[127.0.0.1]:10026; from=<

user1@test.tt> proto=ESMTP helo=<mail1.test.tt>
Dec 6 13:02:27 mail1 postfix/smtpd[48259]: NOQUEUE: reject: RCPT from mail1.test.tt[x.x.x.x]: 553 5.7.1 <
admin@mail1.test.tt>: Sender address rejected: not logged in; from=<
admin@mail1.test.tt> to=<
user1@test.tt> proto=ESMTP helo=<mail1.test.tt>
I am still looking for a solution to make both steps to work, there is any way to exclude an account from being check on the second steps that live out side of the server on split domain?

I am not shure if placing a PMG(Proxmox Mail Gateway) before as a router for mails could solve it.
I will build a lab and i will feed you folks!
Maybe if i do the enforcing and avoid the emails reaching the server zimbra A by the transport in the PMG and send them to server zimbra B from the PMG could solve the problem.
I will test it and feed you.
