Make Gmail send automatic canned responses for email it gets via POP

Question

I have email from my personal domain POP'ed by my Gmail account. It works beautifully, except that it can't seem to do auto-replies.

That means that I can't have an away message when I'm on vacation. And it means I can't create filters using canned responses.

(I know that Canned Responses only apply to new, incoming messages that arrive through SMTP [directly sent to Gmail], not to messages fetched through POP3.)

• How can I make this work within Gmail?
• If I don't have access to mail forwarding on my old account, what other options do I have?

Answer 1

Short answer

Instead of using POP use email forwarding from your other account to be able to use Filters and Canned Responses in Gmail

Explaination

it can't seem to do auto-replies

I beg to differ.

Make sure Canned Responses is activated:

Then you create a filter for emails that are sent to your old email address:

to:([email protected])

EDIT: Note that this will not work for mails fetched through POP3, only for forwarded messages. If your old account has an auto-forwarding feature, that's the way to go. (The other answer here pointed this out.)

You call the filter, say, Old. Then you select a canned response for that filter. Actually, you don't even need to do that. You can autorespond to these emails just the same just by creating a filter for them.

Look at this screenshot:

Answer 2

Canned Responses (as Forwarding and the Vacation Responder) only apply to new, incoming messages that arrive through SMTP (directly send to Gmail), not to messages fetched through POP3.

So I've written an Apps Script that will just work for any incoming mail! http://www.xpos.nl/xpos/download/gs/canned-response-pop3.gs
