Notifications when delivery fails
Mail Log can warn you actively when a delivery fails — so you learn about a mail problem without having to keep looking into the log. The settings are in the options in the tab notifications.
Enabling and choosing recipients
| Option | Default | Meaning |
|---|---|---|
| Enable notifications | No | Main switch. Off by default. |
| Notify super admins | Yes | Send to all super users who have enabled receive system emails in their profile. |
| Additional recipients | empty | Further addresses, one per line or separated by commas. |
| Also as a Joomla private message | No | Additionally files the alert as an internal message (com_messages) for every super user. |
Not too many messages: the throttle
So that a run of failures (a mail server that has gone down, say) does not flood you with hundreds of warnings, Mail Log combines alerts.
With throttle window (minutes) (default 30) you set the minimum gap between two alerts. Further errors within that window are counted but trigger no further message. So you get a warning, not an avalanche.
No loop
The warning mail itself is not treated as a new error when it is sent — Mail Log deliberately prevents one notification from triggering another. That way no alert loop can arise.
Recommendation
On production sites it is worth switching notifications on and keeping at least the super admins as recipients. That way you notice a delivery outage within minutes instead of at the next customer complaint.
