In my Phabricator instance I have a personal Herald rule to add me as auditor on new commits. That works like a charm. However after recent Phabricator update I started to get an e-mail about every commit where I've been added as auditor OR maybe just every commit ever created. I haven't changed anything in setting to enable some additional e-mail notifications.
My guess is that, the E-mail preferences section was created or was changed to give you more control and now I'm getting e-mails for actions I haven't received them before.
{F220363}
Since my own Herald rule added myself as auditor, then this should be considered as my own activity and I shouldn't get any e-mail notifications about it.
Here is how commit used to look before:
{F220368}
And here is how it looks now (new commit made after I updated Phabricator):
{F220370}
Obviously the "Commited ...." line isn't necessary, because it's commit we're looking at :)
From last image I can figure out that Herald is acting from it's own user and that's why I might be getting e-mail for "A commit has auditors added". I'm interested in that e-mail of course of new auditors were added, but not when my own Herard rule added me and notified myself about that fact :(
