VestaCP mail not working – How we tackle it

by | Feb 5, 2021

Is your mail not working in VestaCP? We can help you in tackling it.

Usually, there are many reasons for email errors to arise in VestaCP. Some of them are spam issues, update issues, permission issues, and so on.

Here at Bobcares, we have seen several such VestaCP related errors as part of our Server Management Services for web hosts and online service providers.

Today we’ll see the different causes and their respective fixes for the VestaCP mail issue.

 

How we fix the VestaCP mail not working problem?

Now let’s see how our Support Engineers fix this error for our customers.

 

1. A spam issue causes mail not to work

In most cases, the SPAM rules are too restrictive. So we change the spam score. For that, here are the steps that we follow.

1. First, we access the file /etc/exim4/exim4.conf.template by running the below command.

vi /etc/exim4/exim4.conf.template

2. Next, we change the SPAM score from 50 to a more permissive 20.

SPAMASSASSIN = yes
SPAM_SCORE = 20
CLAMD = yes

3. Finally, we save and quit the file.

 

2. A update issue in VestaCP

Every time, when VestaCP performs an update, there are chances for the update to stop or stay incomplete due to various reasons. So if the update is not fully completed then it causes mail issues.

So to solve this issue, we run the below command

/usr/local/vesta/bin/v-update-sys-vesta-all

After that, we restart the server.

 

3. A namespace issue causing VestaCP mail not to working

Sometimes the namespace issue of dovecot leads to the mail problem. So in order to solve this, we edit the file /etc/dovecot/dovecot.conf.

vi /etc/dovecot/dovecot.conf

Then we add the following code into it.

namespace inbox {
inbox = yes
}

This generally fixes the mail problem.

 

4. Firewall problems – A permission issue

A firewall can also cause issues in email. Especially the ClamAV causes these email problems. ClamAV is an open-source antivirus engine for detecting Trojans, viruses, malware, and other malicious threats.

We’ve seen in some cases that the ClamAV lost the permissions on some folders causing email problems.

So we correct the permission using the below commands.

сhown clam:mail /var/run/clamav/

This must fix the VestaCP mail problems.
