<blockquote>

<p>Jun 24 11:57:13 mx1 postfix/smtpd[2667]: NOQUEUE: reject: RCPT from

</blockquote>
|
|
<p>This error is caused by incorrectly configured mail client application, not a
|
|
server issue.</p>
|
|
<p>All mail users are forced to perform SMTP auth before sending email, so you
|
|
must configure your mail client applications (Outlook, Thunderbird, ...) to
|
|
enable SMTP authentication.</p>
|
|
<h3 id="sender-address-rejected-not-owned-by-user-userdomainltd">Sender address rejected: not owned by user user@domain.ltd</h3>
|
|
<p>This error is caused by restriction rule <code>reject_sender_login_mismatch</code> in
|
|
Postfix parameter <code>smtpd_recipient_restrictions</code>, in file <code>/etc/postfix/main.cf</code>:</p>
|
|
<pre><code>smtpd_recipient_restrictions =
|
|
...
|
|
reject_sender_login_mismatch,
|
|
...
|
|
</code></pre>
|
|
|
|
<p>It will reject the request when $smtpd_sender_login_maps specifies an owner
|
|
for the MAIL FROM address, but the client is not (SASL) logged in as that MAIL
|
|
FROM address owner; or when the client is (SASL) logged in, but the client
|
|
login name doesn't own the MAIL FROM address according to $smtpd_sender_login_maps.
|
|
Check <a href="http://www.postfix.org/postconf.5.html#reject_sender_login_mismatch">manual page of Postfix configuration file</a> for more details.</p>
|
|
<p>Removing <code>reject_sender_login_mismatch</code> and restarting Postfix service fixes
|
|
this issue.</p>
|
|
<blockquote>
|
|
<p>If you want to allow some users to send as other users, or allow all users
|
|
to send as their alias addresses, or allow member of mail list/alias to send
|
|
as mail list/alias, you should try iRedAPD plugin <code>reject_sender_login_mismatch</code>
|
|
instead (requires iRedAPD-1.4.4 or later releases).</p>
|
|
<p>Read comments in file <code>/opt/iredapd/plugins/reject_sender_login_mismatch.py</code>,
|
|
then enable it in iRedAPD config file <code>/opt/iredapd/settings.py</code> (<code>plugins =</code>),
|
|
restart iRedAPD service. That's all.</p>

|
|
<p>It means the maximal number of addresses that virtual alias expansion produces
|
|
from each original recipient exceeds hard limit, please either increase the
|
|
hard limit (default is 1000), or reduce alias members.</p>
|
|
<p>To increase the limit to, for example, 1500, please add below setting in
|
|
Postfix config file <code>/etc/postfix/main.cf</code>:</p>
|
|
<pre><code>virtual_alias_expansion_limit = 1500
|
|
</code></pre>

<p>This error means Amavisd service is not running, please try to start it first.</p>
|
|
<ul>
|
|
<li>RHEL/CentOS/FreeBSD/OpenBSD: <code># service amavisd restart</code></li>

<p>After restarted amavisd service, please check its

<a href="./file.locations.html#amavisd">log file</a> to make sure it's running.</p>
|
|
<p>Notes:</p>
|
|
<ul>
|
|
<li>At least 1GB memory is required for a low traffic mail server. If your
|
|
server doesn't have enough memory, Amavisd may stop running automatically after
|
|
running for a while. If it's just a testing server, you can follow
|
|
<a href="./completely.disable.amavisd.clamav.spamassassin.html">our tutorial</a>
|
|
to disable some features of Amavisd to keep it running, or disable it completely.</li>
