# 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*.

<div class="callout info" id="bkmrk-this-is-part-of-the-">**This is part of the Free version.** The e-mail alert and the Joomla private message exist in both versions — they were part of Mail Log from the start and stay that way. What the Pro version adds in the same tab are two things: the extra route through a *webhook* (see *Alert channel*) and the periodic *report*.

<table class="table" id="bkmrk-optiondefaultmeaning"> <thead> <tr><th scope="col">Option</th><th scope="col">Default</th><th scope="col">Meaning</th></tr> </thead> <tbody> <tr><td>Enable notifications</td><td>No</td><td>Main switch. Off by default.</td></tr> <tr><td>Notify super admins</td><td>Yes</td><td>Send to all super users who have enabled *receive system emails* in their profile.</td></tr> <tr><td>Additional recipients</td><td>empty</td><td>Further addresses, one per line or separated by commas.</td></tr> <tr><td>Also as a Joomla private message</td><td>No</td><td>Additionally files the alert as an internal message (com\_messages) for every super user.</td></tr> </tbody></table>

## 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.

<div class="callout info" id="bkmrk-with-throttle-window">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.

</div>## 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.
