The periodic report (Pro)
WirdPro synchronisiertversion. …This feature is part of the Pro version of Mail Log. What
the Free version does is covered under Free version and Pro version.
The dashboard answers the question "is mail still working?" — but only when somebody looks. The report turns that round: it arrives on its own, at a fixed interval, by e-mail.
What is in it
The subject line already carries the verdict: whether everything is fine, how many messages could not be delivered, or that your sender domain needs a look. A subject line that always reads the same does not get opened.

Switching it on
Interval and period have to match. A 7-day report running daily repeats almost the same figures every day; a 24-hour report running weekly misses six days. Set the task's execution rule to the same interval as the period you chose.
Quiet periods
If nothing was sent and nothing is wrong, no report is sent by default. An all-clear that looks the same every week stops being read after the third one — and so does the fourth, which had something to say.
If you want the sign of life anyway, switch on Send even when nothing happened. A failing DNS record triggers a report even in a quiet period, by the way — that is precisely when it is news.
What the report does not contain
No message bodies, no recipient addresses, no attachments. The report is plain text and holds nothing but figures, extension names and server messages.
That is deliberate: it is the only thing this extension sends out of its own accord. A report that needed guarding as carefully as the log it summarises would have missed its point.
