Add email notification for certain errors

[m-r-c]

If the call to ANDS succeeds, but the system fails to save the DB record, then there would be a DOI without a landing page (unless a custom page was used). If this happens, then we need to send an email alert to ALA Support.

Under review. I can't create more labels though.

ngix was complaining when trying to run with ansible.

Visual code inspection looks fine and sensible.

What nginx errors did you get? Bear in mind that our current nginx role won't work if you run it against a target vm that already has apache installed (you can just stop apache and it then it should work, or start from a clean vm).

We also have a problem with ssl config on vagrant vms at the moment.

Apache already bound to port 80 was straightforward and yes stopping it was the only thing required.

This below is what I got afterwards, not sure exactly what the issue is.

Finally I have to run dos2unix on ala-install\ansible\roles\mongodb\files\disable-transparent-hugepages (and add an empty line so git accepted it as change) as the windows new lines were breaking the script.

Yesterday evening the error went away. I didn't do any changes.
