I ran into this problem as well. So, now, as standard practice, when I set up forwarding between GMail accounts, I add a single filter to the account being forwarded:

    Matches: -96f0f0036730a7d970a678e8f933e8b7
    Do this: Never send it to Spam

The string is just a random hex string, the minus (-) tells it to match all messages that do not contain this string. No message should ever contain it, so no message should ever be sent to spam in the original account. Once it gets to the end account, GMail will still filter it and put it in Spam if it is spam.

That's clever but you can just match is:spam and never send those to spam, essentially turning off the spam filter, not bypassing it.

    Matches: is:spam
    Do this: Never send it to Spam

Unfortunately, you can't use "in:", "is:", "label:", or "has:star" in filters. Filters are applied before these things are determined. If you try to, you get the following message from GMail:

Filter searches containing "label:", "in:", "is:", or stars criteria (i.e. "has:yellow-star") are not recommended as they will never match incoming mail. Do you still wish to continue to the next step?

It's worked for me for years: http://i.imgur.com/bUB3u.png

This works because this filter will match every mail, not just the mails that have the spam label. In the end it does what you wanted but the error is still right.

Odd. I've never gotten it to work. I tried again today just to see if they may have changed that, but still gives me the error.

I think I remember seeing the message actually. You just blow past it and setup the filter, and it'll work, I think.

Is that the same as marking things "Not Spam"? As in, does it lower the quality of Gmail's spam filter?

I specifically tested for this when consolidating various Gmail addresses behind an Apps account, and my fix was similar: a match on * seems to include spam.

It's slightly bizarre that the email forwarding you can configure in settings would not skip all spam checks, and not even indicate as much.

A lot of people forward their email through gmail account exactly because of this feature - to filter out spam, since gmail filter is one of the best.

I did this as well, and it has been working great for me for a few years. A month ago I noticed by chance that it had stopped forwarding 12 hours earlier for no apparent reason. Deleting the rule and recreating it got it working, but it got me thinking of doing a more robust solution.
