In my case I'll soon be watching 3 mail aliases on bugzilla, which means plenty of mail each day. It would be convenient if there was a way for bugzilla to add who the bug is assigned to ( aka, which alias I'm watching it's coming from ) so I can use my mail filter to filter by assignment into different folders.
currently in the mail header there is an X-Bugzilla-Reason, which is set to AssignedTo, it would be nice if that could change to be AssignedTo-Bla@gentoo.org.
If bugzilla doens't have an option like this, feel free to close this bug ;)
I researched this and there was no variable present able to do this. Sorry.
