Topic: Features iRedAdmin-Pro-MySQL

Hi,
Is there any possibility of design or inclusion of features for "Sender & Recipient Throttling" (Max message size of outgoing email single, Max message size of all outgoing emails per unit time, Number of outgoing emails max per time unit, Number of incoming emails max per time unit) for iRedAdmin-Pro-MySQL?
Or how to implement this manually?
Tks

Re: Features iRedAdmin-Pro-MySQL

Hello,
I started using iRedMail recently and am still studying its operation to start the migration of our current platform.
Why Spamassasim is disabled by default? It is recommended to activate it? How to activate it to work in conjunction with other applications?
Very tks

SpamAssassin will be invoked by Amavisd, so we don't need daemon "spamd" running.

Re: Features iRedAdmin-Pro-MySQL

The question above relates to the possibility of setting up automatic filters for incoming messages and classified as spam and they are saved in the spam (junk) users.

So is writing SpamAssassin flags in the headers of incoming messages? There is another way that can be done this sort and filter?

Re: Features iRedAdmin-Pro-MySQL

SpamAssassin will insert SPAM related headers/flags in email, what you need to do is moving these SPAM into Spam/Junk folders automatically.

You can find settings like below in /etc/dovecot.conf (RHEL/CentOS) or /etc/dovecot/dovecot.conf (Debian/Ubuntu/openSUSE):

protocol lda {
     [...]
     sieve_global_path = /var/vmail/sieve/dovecot.sieve
     [...]
}

And you can find a sample sieve rule here: /var/vmail/sieve/dovecot.sieve.sample, simple rename it to "/var/vmail/sieve/dovecot.sieve" will move SPAM mails into Spam/Junk folder.

Re: Features iRedAdmin-Pro-MySQL

Hi,
I have checked the messages as they come - a lot of spam - have no flag in headers SPAM-xxx. Does SpamAssassin is not working?
How can I also implement checking of RBLs?
Tks

Re: Features iRedAdmin-Pro-MySQL

You can check spam status in Amavisd log file, it's /var/log/maillog (RHEL/CentOS/FreeBSD) or /var/log/mail.log (Debian/Ubuntu) or /var/log/mail (openSUSE).

For example:

# grep 'amavis' /var/log/maillog

Search 'RBL' in this forum will give you some useful reference posts:

Re: Features iRedAdmin-Pro-MySQL

I found the following entry in amavis log :

Re: Features iRedAdmin-Pro-MySQL

No such file amavisd.conf in  /etc, /etc/amavis or /usr/share/amavis . In any of the files in conf.d directory, no reference to the settings.

Please let me where is located the configuration file.

Tks

Re: Features iRedAdmin-Pro-MySQL

It's defined in /etc/amavis/conf.d/20-debian_defaults on Debian/Ubuntu.

$sa_tag_level_deflt  = 2.0;  # add spam info headers if at, or above that level
$sa_tag2_level_deflt = 6.31; # add 'spam detected' headers at that level
$sa_kill_level_deflt = 6.31; # triggers spam evasive actions

Your mail log shows its spam score is "Hits: 9.948":

Did you add this mail domain in Amavisd "@local_domains_maps" in /etc/amavis/conf.d/50-user? like below:

@local_domains_maps = ['u1004.iredmail.org', 'YOUR_DOMAIN_NAME'];

Don't forget to restart amavis service to load changes.

Re: Features iRedAdmin-Pro-MySQL

OK!
The settings in 20-debian_default are correct ($sa_spam_subject_tag = '***SPAM*** '; $sa_tag_level_deflt  = 2.0; $sa_tag2_level_deflt = 6.31; $sa_kill_level_deflt = 6.31;).
In file 50-user just configured the local domain (default domain configured on installation iRedMail).
But this mail server will provide other domains. For each new domain set up I must manually enter the 50-user file for Amavis add spam info headers?

Yes. Amavisd can't lookup new mail domains from MySQL/LDAP.

sorry Zhang,
this solution (dovecot.sieve rename) works even if i have enabled "quarantene"?

bye bye and thanks!!
