<p dir="auto">The sorting in the according public folder happens in a global sieve<br>

<p dir="auto">the sieve part seems to be very tricky.<br>
My test is now working with a public folder and I have a<br>
"sieve_before" script in place which works for rules of the<br>
private namespace.</p>
<p dir="auto">But when the rule shall "fileinto" a public folder, the mail isn't<br>
filtered (moved) and syslog says<br>
dovecot: lmtp(.): Error ... sieve...: Mailbox doesn't exist.</p>
<p dir="auto">After some tests I found out it always looks in the private (or shared)<br>
namespace for that specfied folder.<br>
Do I miss a config option to let dovecot sieve "fileinto" a public<br>
namespace folder?<br>
I use dovecot version 2.2.13.</p>

<p dir="auto">We „fileinto“ in this manner :</p>
<pre style="background-color:#F7F7F7; border-radius:5px 5px 5px 5px; margin-left:15px; margin-right:15px; max-width:90vw; overflow-x:auto; padding:5px" bgcolor="#F7F7F7"><code style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0" bgcolor="#F7F7F7">fileinto „Namespace/folder“;
</code></pre>
<p dir="auto">The procedure in our setup is like this:</p>
<ol>
<li value="1">Virtual alias for each public-Folder email address within postfix:</li>
</ol>
<p dir="auto">Pattern:<br>
<a href="mailto:folder@domain.tld" style="color:#3983C4">folder@domain.tld</a> listadm+Namespace/<a href="mailto:folder@domain.tld" style="color:#3983C4">folder@domain.tld</a><br>
Example:<br>
<a href="mailto:info@domain.tld" style="color:#3983C4">info@domain.tld</a> listadm+Verteiler/<a href="mailto:info@domain.tld" style="color:#3983C4">info@domain.tld</a></p>
<p dir="auto">Verteiler is the namespace, info the mailbox. listadm is a pseudo user in this context which holds the ACL for fileinto the resulting mailbox with proper permissions.</p>
<ol>
<li value="2">Disassemble the virtual alias address with sieve:</li>
</ol>
<p dir="auto">Excerpt of the script. It is actually more code because we sort out spam for public folder. German comments, sorry.</p>
<pre style="background-color:#F7F7F7; border-radius:5px 5px 5px 5px; margin-left:15px; margin-right:15px; max-width:90vw; overflow-x:auto; padding:5px" bgcolor="#F7F7F7"><code style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0" bgcolor="#F7F7F7"> # Hat Subadresse?
if envelope :matches :detail "to" "*"
{
# Adressaufbau: listadm+Namespace/liste@
# ${liste} wird Namespace/box
set "liste" "${1}";
}
[…]
fileinto "${liste}";
</code></pre>
<p dir="auto">I can send you the whole script if you need.</p>
