I have a Gmail account and a work email account which is not Gmail. My Gmail fetches my work account and places these emails under a special label. Good so far.
We have a request tracker at work, which sends emails with requests and a fair amount of spam to may work account—this is then fetched by Gmail.
I'm afraid of starting to report this fetched spam to Google as spam (because it comes from the request tracker email address) because then regular requests might be marked as spam as well. How is this done by Google? Is spam classification done by content/address/both? Is it safe to start marking spam? Can I do anything about it?
The best solution would be to prevent spam to be accepted by request tracker, but this is not possible right now.
