  • Is it a VPS on Linode/DigitalOcean/Amazon AWS/...? usually VPS vendor offers another layer of firewall, you need to make sure it doesn't block these network ports.

    I don't believe so. I flushed my iptables record. Everything else is from a clean install of the script.

    Just try to connect to port 25/587/... from another EXTERNAL server.

    2: Again, check /etc/dovecot/dovecot.conf, make sure LMTP service is listening on 0.0.0.0, so that server A/B can connect and deliver emails to each other.

  • 12/05/18--23:19: Re: Sending Bulk mail
  • Is it wise to send 5 000 mails in 1 row ?

    or 20 000 in 1 batch

    I can do it, and i will see what the affects are ... but i would like to prepare myself.. (that is the reason i ask this question)

    Are there base rules to avoid that my mailserver is blacklisted. etc.

            address = 0.0.0.0
            port = 24
        }

    Hi,

    as you know some time email account was stolen and used for send spam. So we have setup a limit of 24 emails per day via iredapd and throttle plugins. All works fine but today we have find a spammers that was able to bypass limit and send more than 5000 emails in few hours. Here the logs:

    From Iredapd logs:

    2018-12-06 02:14:59 INFO 54.232.242.3 RCPT, serve@ammsegurancas35.net => #central.bb.4873@ammsegurancas35.net -> adrianolfreitas@hotmail.com, REJECT Quota exceeded (number of mails in total) [0.0036s]

    Iredapd understand that the limit for account has been exceeded, but Postfix not reject/deny the users.

    How is possibile? Could be because the spammers open an SMTP session and use always the same for sent all emails?

    Our Iredapd version is 2.0.

    Thanks

    Zhang Thanks for replying. Actually there was nothing in apache log. ( /var/log/apache) All files were empty. Unfortunately, I have reinstalled Ubuntu.
    But real problem i am facing is that this is my ip 192.99.70.219. after installing iredmail into it the url is 192.99.70.219/iredadmin.
    I want to point  my domain to this ip. e.g my domain is example.com
    I want to point mail.example.com that points to 192.99.70.219/sogo . Can you please help me with that?
    https://docs.iredmail.org/setup.dns.html
    I have read your documentation but unable to achieve that
    Also can i point my orginal domain to ip and alias as above
    Thanks

    Solved!

    Fix: I had in virtual host in nginx rewrited all access to the mail webpage to https://www... postfix and sogo probably looked for the server hostname, which was not www.XXXX

    here is the dovecot sieve log for an email that never showed up under the schedule user account, and the dovecot log doesn't have anything for this user at that timestamp.

    It think Amavisd still logs detailed log as you wish, but your "grep" got wrong log lines. I suggest double check, for example, run command "less /var/log/maillog", then search "amavis".

    I can guarantee those log entries are not happening. I have tried setting the log_level from 0 to 5 in amavisd.conf, and there is no difference in the log output no matter what I set the log_level. I am  linux system administrator, and I know how to tail, less and grep. I am not seeing those entries in the log. As I said, they were there a couple of week ago, and now they are not.

    Update - it seems that neither inbound nor outbound throttling is working. The database table throttle_tracking is being updated with the cur_msgs incrementing properly the tid appears correct, but it seems that the system isn't reading the settings from the throttle table. My test account is set to throttle at 3 messages outbound and 4 messages inbound, but I send as many emails from the account as I want, and all inbound mail is arriving as well.

    Try to turn on debug mode in iRedAPD, it logs more detailed message for troubleshooting.
    FYI: https://docs.iredmail.org/debug.iredapd.html

    This user is throttled to max 3 outbound per day. I send 5, and they all went through

    here you have the problematic part:

    The logic is: If you host domain "example.com" on iRedMail server, then you remove it, all address *@example.com become invalid/dead. So we need to remove them also.

    The problem of the logic of your suggestion is: if we remove domain but still keep the destination forwarding addresses, many addresses are invalid/dead, if you don't activate mail service for this remove domain somewhere again, emails sent to them will be always bounced/rejected.

    Sorry Zhang but I have to strongly disagree here - there's no logic about deleting forwardings belonging under different domain than I am deleting. That those mails will be bounced (if the domain/mailbox/whatever isn't created elsewhere) is the correct solution (so the administrator will get a hint about forgotten forwarding in different domain that is not working).

    I found this out after few days when these forwardings weren't working without any notification from Iredmail or anything, because it just silently stopped forwarding.  Situations when this can happen are a bunch, for example mailserver migration, DNS switching..

    Just imagine you have one Iredmail with two domains and you are moving one of those domains to another Iredmail server(both domains are variously forwarding emails between each other - pretty usual situation)..
    Et cetera et cetera..

    I  follow the guide 
    1- Sender dependent relay host
    and
    2 -Manage with command line tools

     sql> USE vmail; sql> INSERT INTO sender_relayhost (account, relayhost) VALUES ('user@domain.com', '[mail.gmail.com]:25'); 

    when i send  mail from  user@gmail.com  from sendmail  to    myuser@myserver.com  i recibe this

    Received: from mail.mydomain.com (localhost [127.0.0.1])
        by mail.mydomain.com (Postfix) with ESMTP id A44746548B
        for <myuser@myserver.com>; Thu,  6 Dec 2018 11:14:23 -0300 (-03)
    X-Virus-Scanned: Debian amavisd-new at mail.mydomain.com

    Plz help i m stack here!

    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?

    Postfix will send info to iRedAPD TWICE for EACH email, with protocol_state == RCPT and END-OF-MESSAGE.
    These skipped plugins are applied in RCPT state, and you didn't copy its log from iRedAPD log file.

    Throttling for max messages is applied in RCPT, please check iRedAPD log again, copy them here for troubleshooting.

  • OK, here's a quick solution: add line below in Amavisd config file (better at the bottom of config file to avoid unexpected overwritten), then restart amavisd service:

    $log_templ = $log_verbose_templ;

    - Do these 2 users have personal filter rules with forwarding / redirect rules configured with Roundcube/SOGo?
    - What's the log in /var/log/dovecot/lda.log?
    - What's the content in /var/vmail/sieve/dovecot.sieve?

    I want to point mail.example.com that points to 192.99.70.219/sogo

    You need to add a new virtual web host in Nginx, and set its server name (in nginx config) to mail.example.com.
    You can simply copy /etc/nginx/sites-available/00-default-ssl.conf directly, then replace server name, also remove the "include /etc/nginx/templates/..." lines that you DO NOT WANT (keep the ones you need).

    After that, create a symbol link of /etc/nginx/sites-available/<your-new-file>.conf to /etc/nginx/sites-enabled/, restart Nginx service.

    I suggest check some Nginx tutorials to understand how to add new virtual host. it's not hard at all, just need some practice.

    Unfortunately, iRedAPD-2.0 has a bug that it doesn't treat address leading with '#' (e.g. '#user@domain.com') as a valid email address, so it's bypassed.

    iRedAPD-2.1 (and later releases) fixed this issue. So please upgrade. smile

    ==== UPDATE ====

    Here's patch for iRedAPD-2.0 to fix it if you don't want to upgrade right now:

    An update on this issue
    ====================
    The solution to my case is here: https://www.thesudoer.com/?p=264

    Also, I tried both HAProxy and Nginx for reverse proxy. Both worked just fine with iRedMail 0.9.8.
