Gmail – Some Incoming Messages Do Not Word Wrap

Filters are not processed when you mark a message as not spam. They are only processed when the message first arrives in your mailbox.

You have two choices:

1. Manually forward them when this happens.
2. Use a second account which reads the mail from this account via POP3 and has all of the forwarding rules you defined before.

The first option is self explanatory. It's important to note that these kind of forwards are not the same as a forward invoked by a filter. The two main differences are that you will see quoted text with the former, and the 'to' address will be different as well.

The second option involves setting up another email address and exporting (and deleting) all of your filters from your old account and importing them into that new account. Then set up a filter on the top of the new account which will never send messages to spam. Next, set up the new account to read the mail from the old account using POP3. Since the email will be read via POP3, it will read mail that was previously marked as spam but was then moved to the Inbox. The only disadvantage with this method is that it won't be instantaneous. You could try to increase the frequency the POP3 is read, but that's about it.

The spellcheck that marks words spelled incorrectly with a red squiggly line comes from your browser. You'll need to update that dictionary if you want words like "inbox" marked in the good and clear.

Gmail's spellchecker doesn't kick in until you hit the "Check Spelling" link upper-right to the email body. Any words spelt wrong will then be highlighted on a yellow background.
