Hello,<br>
I've got a newly setup Kolab 3 installation running on Linux Mint 15
(based on ubuntu 13.04).<br>
<br>
I've hit an issue trying to use it as my smtp for sending email,
both from thunderbird on a different computer and from roundcube. <br>
<br>
Every time I try to send an email I get the error:<br>
An (SMTP) error occurred while sending mail. The server
responded: 5.7.1 <DATA>: Data command rejected: Sender access
denied.<br>
<br>
This is with thunderbird set to use starttls on port 587. I'm using
my standard Kolab User I set up in kolab-webadmin, using the same
auth I use for imap access (with the uid as username).<br>
I've tried with a POSIX backed user with no change.<br>
<br>
The only reference I can find to this error is in the source, in
<meta charset="utf-8">
kolab_smtp_access_policy.py<br>
This lead me to:
<a class="moz-txt-link-freetext" href="http://docs.kolab.org/en-US/Kolab_Groupware/3.0/html/Architecture_and_Design/chap-Architecture_and_Design-Kolab_SMTP_Access_Policy.html">http://docs.kolab.org/en-US/Kolab_Groupware/3.0/html/Architecture_and_Design/chap-Architecture_and_Design-Kolab_SMTP_Access_Policy.html</a><br>
and with more info:

<br>
From this and more googling of the subject I believe I need to get
kolabAllowSMTPSender attribute(s?) on my kolab user to allow it
access to the smtp, but I don't know any way to do this.<br>
<br>
I've found a workaround here:

To be clear, in /etc/postfix/main.cf I replaced:<br>
<br>
submission_data_restrictions = check_policy_service
unix:private/submission_policy<br>
<br>
with <br>
<br>
#submission_data_restrictions = check_policy_service
unix:private/submission_policy<br>
submission_data_restrictions =<br>
<br>
But I am concerned about any security ramifications?<br>
Can anyone shed light on this problem?<br>
<br>
Cheers,<br>
Andrew<br>
