Title: Sets deprecation age for mails sent by check_mail_loop from 24h to 2h Class: feature Compatible: compat Component: checks Date: 1706618999 Edition: cre Level: 1 Version: 2.2.0p21 Mails sent by <code>check_mail_loop</code> had been deprecated only after 24h, which potentially resulted in thousands of mails in circumstances when sent mails could not be processed for whatever reasons. This change lowers this age to 2h resulting in 'only' 120 mails (for this active check being executed every minute).
