Can't anymore send mail - Carbonio General https://community.zextras.com/forum/carbonio-general-thread/cant-anymore-send-mail/ Zextras Community Discussion Board en-US Thu, 05 Mar 2026 14:37:11 +0000 wpForo 60 RE: Can't anymore send mail https://community.zextras.com/forum/carbonio-general-thread/cant-anymore-send-mail/#post-10332 Thu, 17 Apr 2025 14:03:34 +0000 Hello,

There is no process listening on port 20025, as ports ending by 25 i see only 7025 and 10025.

But it perhaps linked to the bunch of anomaly mesages I get every day as :

Apr 17 15:48:28 mail systemd: Stopped NGINX Carbonio ClamAV signature provider sidecar.
Apr 17 15:48:28 mail systemd: Started NGINX Carbonio ClamAV signature provider sidecar.

About every 15 seconds

grep 'NGINX Carbonio ClamAV signature provider' syslog | wc -l
7474

There is something broken, but I can't find the culprit

Other king of messages found :

Why 20025 port was not working? needs investigation. I would request you to check the consul Mesh interface for any hints of anomaly. you can find the details here.

https://docs.zextras.com/carbonio-ce/html/admincli/mesh/mesh-gui.html

  • setup a ssh tunnel 
  • access the interface via http://localhost:8500

Just to share you some key things:

mailbox is connected to the MTA via 20025 internal port of Consul Mesh but MTA is also listening on 25 port (That's how it receives incoming email). So if you tell mailbox to use the 25 directly it would work but as you can understand this way we are hardcoding ports to the system arch (Bypassing the consul Mesh). For example, mailbox is connected to carbonio-mta (20025), carbonio-clamav (20004) at the mentioned ports. 

That's why I would request and recommend looking into consul mesh interface besides other troubleshooting steps during any issue.

I hope it helps.

😊

Why was it not working with 20025 and is now working with 25 ?
What was the change which broke that part ?

Hi,

I would not recommend changing the port. Because all the basic email components in carbonio is connected/talk to each other via internal port assigned by Carbonio service mesh. Therefore if your Carbonio Mesh is running without any issue, you should be able to send emails. For example, in my environment

zextras@mail:~$ carbonio prov gcf zimbraSmtpPort
zimbraSmtpPort: 20025

zmprov gcf zimbraSmtpPort
zimbraSmtpPort: 20025

#

zmprov mcf zimbraSmtpPort 25

zmprov gcf zimbraSmtpPort
zimbraSmtpPort: 25

And ... I can send mails, but I wonder why 25 has changed to 20025 ?

Regards

Problem solved !

Today I try to get the daily email report but i get a weird message :

/opt/zextras/libexec/zmdailyreport -mFailed to email report using SMTP via '127.78.0.7': Connection refused at /opt/zextras/common/lib/perl5/Mail/Mailer.pm line 163, <CONF> line 625.

There is no process listening on 127.78.0.7 :

netstat -an | grep 127.78.0

Hope a solution.

From today I can't send any mail, after 2 seconds I get a message "Something went wrong".
