Gmail already is free storage, AFAIK it shares you data quota with you Google drive account.
Most likely this is a 'mail-loop' prevention. If you setup two accounts that forward to each other, then emails will be stuck in an infinite loop. Inject a couple of multi-megabyte emails into that loop and you can take down the entire service. This is effectively a DOS attack.
- londons_explore 6y agoIt could also be an implementation detail. Mail messages have a unique identifier. Gmail might just concatenate the mail identifier with your account identifier to use it as a primary key to store your email in the "mails" bigtable. If you send email to yourself, when it comes to put the mail into the mails bigtable, the result will be "primary key already exists, cannot insert"
- prepend 6y agoMaybe similar to this, but it works if my message stays in gmail when I send from my gmail straight to my gmail.
