Do you have the php-imap PHP module installed?
Run the command rpm -qa | grep php (CentOS) or dpkg -l | grep php (Ubuntu) and see if it is listed.

If not, try installing it through the package manager
sudo apt install php-imap (CentOS) or sudo yum install php-imap (Ubuntu)
then restart your web server and the PHP-FPM process (if using PHP-FPM).

Apache: sudo systemctl restart httpd (CentOS)
or sudo systemctl restart apache2 (Ubuntu)
Nginx: sudo systemctl restart nginx
PHP-FPM: sudo systemctl restart php-fpm

php-imap-5.4.16-9.el7.x86_64 is installed

8

5.4 is not supported anymore by Mautic.
You need to upgrade PHP and its modules to PHP 7.2 or 7.3.

I had the same issue, the problem is that the console could use a different folder or instance of PHP.

For instance, my mautic folder-project worked with PHP 7.2, but when I was in the console, the active PHP was 7.4 and this version of php did not have the imap library.

I just installed the imap library in php 7.4 and it works!

10

php -v in the console to see the active php could works

11

I also got the same problem with EJL, anyone knows how to fix that?
my email monitor login test was successful but I can’t fetch them on a cronjob

12

I am now experiencing this issue,

I have php 8 IMAP working, it shows in the system info tab as enabled,

Any ideas on how I could trace this issue?

In Mailbox.php line 542:
                                                                                                
  [Symfony\Component\ErrorHandler\Error\UndefinedFunctionError]                                 
  Attempted to call function "imap_search" from namespace "Mautic\EmailBundle\MonitoredEmail".

php8 is not supported yet … need to be at php 7.4

14

I’m on 4.4 which release PHP 8 support, but either way, I upgraded to 8 to try to remedy the issue but it didn’t work, it started just the same at 7.4

15

I don’t remember about 4.4 supporting php8 then …

You could be right however I been seeing posts in here recommending to stay with 7.4 until Mautic 5 is released.

16

Here is that release

The issue still is not that one however, as PHP version does not fix the issue, now only seeing it with

 php /home/crm.grou.com/public_html/bin/console mautic:email:fetch -v
