Bug 24588: Prevent e-mails from Koha to be flagged as spam
Set the e-mail headers Mailer-X and MessageID by Koha,
to gain a better positive score from the spam filter.
To test:
1) Let Koha send an e-mail message.
2) Check the header of this e-mail message with your e-mail client.
There should be no X-Mailer header with value 'Koha'. If there
is an MessageID header, it is probably set by the MSA, e.g. Exim.
Example:
Message-Id: <E1iyZRY-0006XT-0t@FQDN>
3) Apply patch.
4) Repeat step 1.
5) Check the header of the new e-mail message with your e-mail client.
There should be a X-Mailer header with value 'Koha' and a MessageID
header with a value set by Koha.
Example:
X-Mailer: Koha
Message-Id: <
15807387030.B731e.18490@FQDN>
6) Sign off.
