Anti-spam gateway

texmav — Fri, 27 Feb 2026 14:08:01 +0000

Good morning, I would like to know if it's possible to insert an anti-spam gateway into the mail delivery chain before Carbonio.
The gateway's IP address would then need to be trusted on Carbonio, since SMTP authentication already occurs. Carbonio would therefore only need to perform the entire anti-spam analysis, attachments, etc., but not the SMTP authentication part of the messages (coming from the gateway would fail all SPF checks).
Can you help me and tell me if this is possible?

Need guidence how to calendar syncing in Mobile phones without any third party app

kachavan — Fri, 27 Feb 2026 07:12:21 +0000

Hi,

I have done a setup of carbonio community edition on ubuntu server 22.04. All is working fine. But when I have configured my id in the gmail app of Android and iOS the emails are syncing properly but not the Calendar. And after install the DAVx⁵-Calender+CalDAV and OneCalendar app on mobile respectively the calendar syncing works properly.

What can we do so without installing any other app the calendar syncing should be possible in mobile.?
Please suggest.

Restore Issue – carbonio.service failing, service-discover stopped, inbound mail working

UserCarb001 — Tue, 24 Feb 2026 23:10:42 +0000

Hello,

When checking the Carbonio service at OS level:

sudo systemctl status carbonio

The output is:

× carbonio.service - LSB: Carbonio Services
     Loaded: loaded (/etc/init.d/carbonio; generated)
     Active: failed (Result: exit-code) since Tue 2026-02-24 16:48:27 -06

This indicates that the main carbonio.service fails when managed through systemd.

zmcontrol Status

Despite the above failure, when executing:

zmcontrol status

Most services appear operational, but we observe:

service-discover        Stopped

All other core services (amavis, antispam, antivirus, directory-server, mailbox, memcached, mta, opendkim, proxy, stats, config service) report as Running., i can sed mails others domains (gmail, outlook) but not send.

Few issues with install of Zextras

kdmiller45 — Fri, 20 Feb 2026 01:14:34 +0000

when I ran the initial install .sh file I got the following error

Insert the cluster credential password: service-discover: error: unable to open /etc/zextras/service-discover/cluster-credentials.tar.gpg: cannot find Cluster credential in /etc/zextras/service-discover/cluster-credentials.tar.gpg, please copy the file from the existing server or upload it to LDAP could not find in documentation what the default was since I did not see instructions on how to set it

While running Carbonio Bootstrap It kept finding a port conflict with 25, I killed all processes running on that port and reran it, still came up, so I disabled mta just for now and continued the setup completed with some other error

Creating galsync account for default domain...failed. probably because mta is disabled

I noted the two passwords for service-discover and The PostgreSQL password

any help would be appreciated
