I have set enabled manual polling for forum.mydomain.net and it works like a charm. Fascinating to see how fast the reply pops up on the forum!
Now, my problem is the following: I had previously not used the forum subdomain for incoming email.
reply by email address was
email@example.com was (and still is) forwarded to a gmail account (from which discourse does the pop3 polling).
So, in order for the direct delivery to work, I had to change my
reply by email address to
...@forum.mydomain.net while that works fine, I hesitate to turn the pop3 polling from the gmail account off because chances are that people will still be replying to the old address (without the subdomain) and since those end up in gmail, I need to keep polling it.
My question is: how do I safely shut down the old gmail polling based system?
I have considered forwarding those old emails to the new mail-receiver instead of gmail, but would it work? Because they will still be directed to @mydomain.net and I assume that the mail-receiver will not accept them. And it it will, I don’t know if discourse will accept them because the
reply by email address no longer matches.
In fact, as I think of it, the latter may well be a problem already now when I still emails arriving via gmail.
