    It's like a network issue, not iRedMail configuration.
    Can you connect to port 24 with tool like 'telnet' on localhost, AND from another server (A to B, B to A)?

    I have learned that the setup is other else to have it worked.
    it just configure the right setting on relay. no need to involved lmtp

    Thanks Zhang for your support.

    Hi Zhang,

    The logs in iRedAdmin-Pro show entries like this for a domain admin:

    2018-12-06 15:07:15     user@myserver.example.com     1.2.3.4     Add whitelists for @myserver.example.com: @.yahoo.com.

    If I navigate (as postmaster user) to System -> Anti Spam -> Whitelists & Blacklists I do not see @.yahoo.com listed.

    If I navigate to Domains and Accounts -> usersdomain.com -> White/Blacklist, all four boxes are empty.

    If I log in as the user and navigate to Domains and Accounts -> usersdomain.com -> White/Blacklist, all four boxes are empty.

    The user is complaining that he has whitelsited yahoo.com, but emails from yahoo.com addresses are still being caught in the quarantine.

    Why is this?

    Hi Zhang,

    It's unclear to me from https://docs.iredmail.org/iredadmin-pro … olicy.html which "settings.py" file I should edit to set minimum and maximum password lengths. This is what I have on my system:

    [08:14:31 root@server ~]# grep passwd_length /var/www/iRedAdmin-0.9/settings.py
    #   - min_passwd_length: 0 means unlimited, but at least 1 character
    #   - max_passwd_length: 0 means unlimited.
    min_passwd_length = 8
    max_passwd_length = 0
    [08:15:41 root@server ~]# grep passwd_length /var/www/iRedAdmin-Pro-SQL-2.9.0/settings.py
    #   - min_passwd_length: 0 means unlimited, but at least 1 character
    #   - max_passwd_length: 0 means unlimited.
    min_passwd_length = 12
    max_passwd_length = 0
    [08:15:45 root@server ~]#

    In iRedAdmin-Pro I set up every new domain as follows under "Advanced" settings for the domain:

    * Minimum password length: 12
    * Maximum password length: 0

    However, any user can change the minimum password length to 4, for example, defeating the purpose of setting a server-wide minimum!

    Also, when I try to change the maximum to 0 (for unlimited), when I click "Save changes" the page reloads with the same old value in the box.

    What am I doing wrong? Which "settings.py" file should I be using? And why are the setting in "settings.py" not working?

    Before writing this post I ran

    systemctl restart uwsgi

    to make sure everything was properly set.

    As an ordinary user I even tried setting the minimum password length to 1, and it works! Scary!

    This is the setup.

    Public IP>>firewall/SMTP Proxy>>iredmail server (10.100.100.70)

    The private internal IP of the firewall/proxy is 10.100.100.1

    If we connect to sogo front end, either via the private IP of the iredmail server(https://10.100.100.70/sogo/, on the local LAN OR connecting to sogo via the public IP (through the firewall), we can send and receive email no problem to external and internal accounts. (by internal i mean emailing to myself or another user setup on iredmail)

    However, if we use an IMAP client (mac mail) that connects to the iredmail server on its private IP (10.100.100.70)

    We get a bounceback if we try to email ourselves or another user on iredmail server.

    The error we WERE getting yesterday was an SMTP AUTH error, shown below. (The sogo client was ok, just the IMAP client was failing)

    Dec  6 16:13:00 host1 postfix/postscreen[12198]: CONNECT from [10.100.100.1]:53738 to [10.100.100.70]:25

    However today the problem has gone away...we have no idea why.

    Generally if you can send ok from the web client (sogo) but an IMAP client connecting to the iredmail server directly fails, is this really an imap client issue only, or a iredmail issue? (just for future reference)

    BTW MX records, DNS all seem to be ok, as the webmail client works ok, so i figured i can rule that out.
    Sorry for the strange question, but any help or advice is appreciated. thanks

    Here is a log of sending using webmail client sogo: working.

    We did the following actions yesterday based on the docs. Can you tell me if this is ok or bad?

    1.to add the smtp proxy to the whitelist, and checked using:

    python /opt/iRedAPD-2.2/tools/wblist_admin.py --add --whitelist 10.100.100.1

    python /opt/iRedAPD-2.2/tools/wblist_admin.py --list --whitelist
    * Establishing SQL connection.
    * List all inbound whitelist for account: @.
    /usr/lib/python2.7/dist-packages/pymysql/cursors.py:158: Warning: '@@tx_isolation' is deprecated and will be removed in a future release. Please use '@@transaction_isolation' instead
      result = self._query(query)
    10.100.100.1

    We also added the following to the /opt/iredmail/settings.py file

    # Steve Added to try to stop the following error:
    # "Recipient address rejected: SMTP AUTH is required for users under this sender domain"
    MYNETWORKS = ['10.100.100.1']

    So to be clear, today it seems emails are all working now, but we don't know why they were not before.

    Thank you so much..

  • 12/07/18--04:02: rsyslog
  • I would like to configure the server to send the maillog to rsyslog which then puts the log entries in a MySQL database, making it easier to write application to continuously analyze it for blacklisting or other problems.

    I noticed that rsyslog has been configured but I can't figure out is anything is enabled

    Can I fiddle with rsyslog (like removing and starting from scratch) without messing with the iRedMail and iRedAdmin installation?

    EDIT: to the primary question in this thread, I see there almost similar pattern in user SQL library - the SQL queries are totally unaware of the mail domain under which the user belongs, couldn't be this the root cause?

    The logic is slightly different than removing a domain, you just remove one user, but the domain is still hosted on your server. So we should remove this user from forwarding destination. isn't it?
    ?

    From admin point of view is better to keep the domains separated - and, moreover, what about users doing self-service? Again, possibly dangerous behavior, there were reasons for creating that forwarding before, it shouldn't dissapear without notice..

    Example:
    I host 2 domains, one has a large mailing list where are people from both domains, moderators of the list have to be notified about user disappearing from the list. Keep the forwarding, send the bounce, don't invent sending moderators notification emails about user deletion in mailing list they moderate..

    Did you change password in iRedAdmin-Pro self-service or Roundcube/SOGo? They are not related, iRedAdmin-Pro settings does not affect Roundcube and sogo.

    I'm a little confused with your real email domain name and the log:

    - The log shows whitelist was added for your local mail domain "@myserver.example.com". So this is a per-domain whitelist (for "@myserver.example.com").
    - You mentioned domain name is "usersdomain.com", i suppose what you mean is "example.com" which is parent domain of "myserver.example.com"? If yes, then this is not matched.

    What i want to know is:

    - Show me the domain name in log in correct format (the @myserver.example.com).
    - Show me the domain name you checked in iRedAdmin-Pro.
    - How can i reproduce this issue step-by-step?

    Hello,
    I have setup the emails accounts on Outlook 2013 first as IMAP, to load the old emails in the accounts, then as ActiveSync. I have a problem with any new email that the accounts are receiving: it duplicate itself as many as it can, until the user delete the received email. After that, the duplicate process stop.
    (the same account set it up on mobile as ActiveSync works fine. Also, no duplicate email appear on mobile even if in Outlook I have more than 100)

    Tell me what I can do to stop this.

    I changes back, and it worked all the way. i don't know why there is problem on that day, but it should be that setting.
    I did not used lmtp presently and it work just as i expected.

    Thanks anyway

    Hi Zhang,

    Thanks for your reply, but I'm confused about why you're confused, as that's a copy and paste of the log from my installation of iRedAdmin-Pro, with my own server's domain anonymised. The user's domain does not appear anywhere in the log.

    I create domain users on my server in the form of clientCode@subdomain.mydomain.com (user@myserver.example.com in my post). I know you recommend against it in iRedAdmin and iRedAdmin-Pro when creating a user, but that's how I choose to do it.

    If you need to know exactly what my domain and sub-domain are, please email or PM me and I'll happily provide them.

    This user tried to whitelist @.yahoo.com for his own domain, let's call it example.NET, not for the whole server. His domain does not show up in the log.

    * I have copied and pasted the format exactly from iRedAdmin-Pro, but only changed my domain to maintain privacy. Since this isn't a networking question the actual domain shouldn't matter. The only domain that is real is @.yahoo.com
    * I don't understand what you mean by "Show me the domain name you checked in iRedAdmin-Pro." Are you looking for a screen capture of something?
    * I don't know how you can reproduce this, that's why I'm asking the question. However, I will ask the user to tell me exactly what he did to white- and blacklist these senders, but I suspect he did so from the drop-down list at the bottom of the quarantine page.

    Thanks.
