Can I use postfix sender_access?

Right, I think it was a bad idea disabling the greylisting. I'll enable it back. Though, I dont want our users to have delay receiving messages from our "known" domain like those hosted in google, yahoo etc. Is there a way to whitelist those domains then greylisting will be bypassed.

Thanks Zhang for your continued support. Really appreciate it.

Just wait for some minutes (maybe up to 30 minutes), and emails will be delivered to your mailbox.

I suggest you (a mail admin) try to understand what greylisting is and how it helps fight spam:

Hi. I have setup a global quota rule in dovecot.conf. Is there any way to change the quota limit for specific users?
Thank you.

If others face the same problem:

- if you add a new domain through iRedMail Webadmin (free Version) it will NOT be excluded from greylisting
- you need to add a record through Cluebring Web Admin. In my case I add new domain testzone.ch
- http://[your domain]/cluebringer
- groups >> internal_domains >> select action -> members >> select action -> add >> Member: @testzone.ch >> save >> Back to Members >> @testzone.ch >> select Action -> change >> disabled -> no -> save

After this change greylisting for authenticated user rolf@testzone.ch is bypassed.


Side note: I'm not too happy how much time this took to track down the problem (investigate code and sql queries). Was expecting the developer(s) of iRedMail know how things work. Instead I got two wrong (misleading) answers.

Could you please show me output of below command?

# crontab -l -u sogo

I fixed cron jobs for sogo user after sent email to mailing list. It should be:

# iRedMail: SOGo email reminder, should be run every minute.
*   *   *   *   *   /usr/sbin/sogo-ealarms-notify

# iRedMail: SOGo session cleanup, should be run every minute.
# Ajust the [X]Minutes parameter to suit your needs
# Example: Sessions without activity since 30 minutes will be dropped:
*   *   *   *   *   /usr/sbin/sogo-tool expire-sessions 30

# iRedMail: SOGo vacation messages expiration
# The credentials file should contain the sieve admin credentials (username:passwd)
0   0   *   *   *   /usr/sbin/sogo-tool expire-autoreply -p /etc/sogo/sieve.cred

By the way, if you want to check these emails, please add an alias in /etc/postfix/aliases like below:

sogo: root

Then execute command:

# postalias /etc/postfix/aliases

We have default alias entry for root user in this file, it's aliased to 'postmaster@xxx' - the admin created during iRedMail installation.

You can add record in SQL table "cluebringer.greylisting_whitelist" to whitelist certain domains. But it's not recommended to whitelist whole big ISPs, because spammers use big ISPs to send spams. it should be fine to whitelist certain sender emails.

iRedMail configures Dovecot to query per-user quota in /etc/dovecot/dovecot-ldap.conf. If you don't need a per-user quote limit, you can remove ",mailQuota=quota_rule=*:bytes=%$" in dovecot-ldap.conf.

Squirrelmail is just a webmail which accesses mailbox via IMAP protocol, it should be ok to setup roundcube and replace it. Mailboxes are still accessible via Roundcubemail.

What else data of SquirrelMail do you want to migrate?

Please follow our tutorial to turn on debug for ldap query in Postfix:

If nothing returned by the command, it means LDAP query doesn't get expected result. Please set "debuglevel = 1" file /etc/postfix/ad_xxxxxxx.cf, it now will print detailed debug message.

By the way, please paste TEXT of file/output instead of screenshot image, text/content in image is not searchable.

Sorry, i forgot that iRedAdmin open source edition won't add new mail domain in Cluebringer '%internal_domains' group.
You can fix it with script shipped in iRedAdmin: tools/sync_cluebringer_internal_domains.py. If the iRedAdmin installed on your server doesn't have this file, please download it in our source code repository, and it will be included in next release:
https://bitbucket.org/zhb/iredadmin-ose … ult/tools/

You need to download below files:

- tools/__init__.py
- tools/ira_tool_lib.py
- tools/sync_cluebringer_internal_domains.py

Hi Zhang,

I believe there was some other problem in the system environment, for in the same way that the error began, he stopped.

I have also adjusted the configuration parameter settings imap_auth_type LOGIN to webmail.

I'll keep watching.

Thank you

Ok, you have fixed it in iRedMail-0.9.0-rc1, but was set by me in

/var/lib/sogo/GNUstep/Defaults/.GNUstepDefaults

from the beginning.

You have given the solution here: mail for local user "sogo" -SOGo Integration-

Many thanks!

Hi Zhang,

I chose to migrate this server (new Debian, daemons, etc.)

So, I believe this point of the update will not interfere in the wake of other recent updates, because the new platform tables and iRedMail will already be adjusted to save quota information in a separate table.

I will do all the other updates - especially the structures of the vmail tables - to be able to generate a dump of the database and restore it on the new platform.

I think that works out. Do you agree?

Tks,

M Martinatti

THX, was empty, have created the crons with

crontab -e -u sogo

The simple uncomment in /etc/cron.d/sogo doesn't worked, unfortunately.

These fixed the issue under Cronjob EMail reminders -SOGo Integration-

I tested spam behaviour with this free online service: http://www.emailsecuritycheck.net/
This service sends seven emails which should get banned. What happend? All emails except for email2 did enter my mailbox:

- 1) Test mail 1/7 (ID=c6nbPKFQuvszu3lCPSHYAA==)
- 2) -> not received
- 3) *** SPAM *** Test mail 3/7 (ID=c6nbPKFQuvszu3lCPSHYAA==)
- 4) Test mail 4/7 (ID=c6nbPKFQuvszu3lCPSHYAA==)
- 5) Test mail 5/7 (ID=c6nbPKFQuvszu3lCPSHYAA==)
- 6) Test mail 6/7 (ID=c6nbPKFQuvszu3lCPSHYAA==)
- 7) Test mail 7/7 (ID=c6nbPKFQuvszu3lCPSHYAA==)


Postmaster received seven emails:

- 1) BANNED contents (application/x-msdownload,.asc,attached.bat) in mail FROM LOCAL [78.47.119.33]:46094 <securitycheck@emailsecuritycheck.net>
- 2) VIRUS (Eicar-Test-Signature) in mail FROM LOCAL [78.47.119.33]:45631 <securitycheck@emailsecuritycheck.net>
- 3) Spam FROM LOCAL [78.47.119.33]:58287 <securitycheck@emailsecuritycheck.net>
- 4) BANNED contents (application/x-msdownload,.asc,attached.bat,attached.bat) in mail FROM LOCAL [78.47.119.33]:39333 <securitycheck@emailsecuritycheck.net>
- 5) BANNED contents (application/x-msdownload,.asc) in mail FROM LOCAL [78.47.119.33]:57379 <securitycheck@emailsecuritycheck.net>
- 6) BANNED contents (application/x-msdownload,.asc,attached.()bat) in mail FROM LOCAL [78.47.119.33]:53361 <securitycheck@emailsecuritycheck.net>
- 7) BANNED contents (application/x-msdownload,.asc,attached\) in mail FROM LOCAL [78.47.119.33]:43625 <securitycheck@emailsecuritycheck.net>


Now my questions:

- why are those emails not moved to junk server side?
- why did postmaster get all those message from iredmail?

This is still a test system. This spam behaviour doesn't seem to be production ready for me.


Do I miss something?

Thanks

How to enable receiving mail sent to user@xxx.xxx.xxx.xxx .... (example: user@198.161.53.3) ?

I need this enabled, since I have old server removed from MX record (Exchange 2003) and new one with iRedMail ... but with same mail addresses ...

Idea is to enable mail forward from old server to new one, but since mail addressess is same I cannot forward to full mail address, so I need to use IP.

This is needed until all users set their new SMTP settings. Sending from exchange to local user... mail is delivered to exchange, so every user has to have two accounts in their mail client (and that is confusing some users), one for old server and one for new, and until all user setup their clients to new mailserver there is posibility that someone send mail using old server to user on same domain and that message will newer get to new server.

I wonna to remove settings for old server from users mail clients and that all mail come to new server.

Sending now to IP address (address is modified) gives me this error:

Delivery to the following recipient failed permanently:

    kmihalj@161.xxx.xxx.xxx

Technical details of permanent failure: 
Google tried to deliver your message, but it was rejected by the server for the recipient domain 161.xxx.xxx.xxx [161.xxx.xxx.xxx].

The error that the other server returned was:
501 5.1.3 Bad recipient address syntax
