Clamav Service

Clamav is an Anti-Virus Service used for detecting virus traces in incoming and outgoing mails and appropriately reporting to users.

Clamav in EPL

Clamav is used and supported from Ensim Pro for Linux v3.7.0 onwards. We were providing this service to our customer in two forms:

1. Ensimized rpm (only in cases where OS compatible rpm were not available) &
2. Third party rpm (when a third party was available and picked up)

De-Ensimizing Clamav

Reasons for de-ensimizing Clamav:

1. Ensimized clamav makes this service tightly coupled with Ensim Pro for Linux rpms.
2. Third Party rpms provided by ensim have stopped supporting clamav on all required OS and versions.
3. Dependency of Ensim for any clamav upgrade.
4. Users stuck up at very old versions of clamav, which have many performance issues.

Result: Customers, dependent on Ensim to come up with hotfix release to upgrade their Clamav, given it is available easily and freely as source or rpm.
