Notifications when delivery fails

~~Wird~~Mail ~~synchronisiert~~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.

The options tab notifications — The tab *notifications*.

Enabling and choosing recipients

OptionDefaultMeaning Enable notificationsNoMain switch. Off by default. Notify super adminsYesSend to all super users who have enabled receive system emails in their profile. Additional recipientsemptyFurther addresses, one per line or separated by commas. Also as a Joomla private messageNoAdditionally 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.
