I am consolidating several Gmail accounts (leaf accounts) in on central account (e.g., central@gmail.com
).
When faced with the choice between :
- Forwarding from each leaf account to the central account
- Checking mail for all leaf accounts from the central account
I took the first option, because it seems instantaneous (while checking happens roughly every our).
I am trying to forward to a different Gmail alias for each leaf account.
Example: the first leaf account (
leaf1@gmail.com
) would forward tocentral+leaf1@gmail.com
.
I then use this forwarded to address as a criterion to create a filter for all mails forwarded from leaf1@gmail.com
.
The problem
I did a few tests, and it appears that the Delivered-To:
field in the forwarded e-mail sometimes refers to the aliased address (central+leaf1@gmail.com
), sometimes it does not (central@gmail.com
).
Several tests were made, with different From:
addresses, and with empty and non-empty mails, and I was not able to find the rule behind that. I am wondering if it is an inconsistency in Gmail's forwarding, or some deterministic rule?
