Debian 13 fresh espocrm installation

[AlexiLaiho]

The `php-imap` package is not required for EspoCRM. IMAP will work without it.

maybe it's time to update the installation instructions and remove it from there?

Is there any official statement about this from the developers?

I do not know much about it and just found out this will be an issue for Ubuntu 26.04 as well because it will not offer a php-imap package too.

Some say install IMAP via PECL or switch to an alternative libary. Some suggested: https://github.com/Webklex/php-imap

Hi Guys,

I’m setting up a native EspoCRM installation on Debian 13 (Trixie) using the default system stack (Apache + PHP + MariaDB, no Docker).

Everything installs and runs fine with the default PHP 8.4, and I was able to complete the installation wizard successfully. However, I ran into an issue regarding IMAP support:

• Debian 13 default PHP = 8.4
• The traditional php-imap package is not available in stable repos
• From what I understand, IMAP was moved to PECL in PHP 8.4
• EspoCRM documentation still lists php-imap as a requirement for inbound email functionality

My questions:

I need inbound email fetching (IMAP) for production use. Questions:
What is the recommended approach for EspoCRM on Debian 13 with PHP 8.4?

1. Should I:
   • Switch to PHP 8.3 (e.g., via SURY) to get php-imap, OR
   • use older version of debian?
   • Install IMAP via PECL / experimental packages, OR
   • Is there an updated/alternative method EspoCRM recommends for PHP 8.4 environments?

Please let me know,
thanks for your time and help.
