Hi, in the last two days, im getting stuck with several messages on queue, around same time, both days. I checked the postqueue this problem:
4Mpr9Z50Y6z1y76       4352 Fri Oct 14 15:37:22 homsens263@xxxxx.tech
                   (connect to 127.0.0.1[127.0.0.1]:10026: Connection refused)
                                               yannick@xxxxx.tech

It seems, from what i searched online problem is related to the amavisd service, i tried to find this service as service amavisd status but it returns that the service unit doesnt exist. I dont know how the easy version runs the service.

Today i tried to telnet the above port (10026) it was returning error, i rebooted the service and the amavisd worked again and the queue sent all mails.

Someone had similar issues and can help me find what can be the issue? Or at least where i can try to find more information about, like logs? Im pretty new to linux mailing

Re: Help with amavisd, stop responding

- The service name is "amavis" on Debian/Ubuntu (and "amavisd" on CentOS).
- iRedMail requires at least 4 GB memory for low traffic production server.

Re: Help with amavisd, stop responding

Hi thanks for your reply. Since its a preproduction server, i was doing regular reboots because i didint have the time to check.

Im going into production and this problem is happening several times.
This server have less than 20 mail accounts, and it have 4gb of RAM, but i cant still pin what is causing the issue. Sometimes, it keeps several days without issues, sometimes i have the issue several times on same day, and the only thing that solves the issue, at least temporarily is rebooting the server.

Is there any log or log file where i can find the reason its crashing or stopping to work?

Re: Help with amavisd, stop responding

When the issue happens, is ClamAV service running?

On the last week, i didnt have any problems. How can i check if the clamav service is running?

The only correlation i found out was a series of messages to the postmaster/admin account not being delivered and on the queue. Since i manually removed all those messages it didnt stopped.

Re: Help with amavisd, stop responding

Since this server has 4GB memory, please try to REDUCE concurrently processed emails to one message by following this tutorial, to prevent ClamAV crash:
