Should I delete old messages?
I already deleted my sent inbox.
How much of my email should I delete?
Use the webmail interface to your account. Usually there is a guage
that shows how much of your disk quota that you have used.
It may not just be disk quota that you have fully consumed. You may
also have a quota as to how many e-mails per month or per day that you
can send, or how many recipient in total (including multiple recipients
per e-mail) that you send per day. Many users don't realize, for
example, that there is a per-recipient maximum quota with a Gmail
account.
Whether it is your quota or the recipient's quota all depends on WHO
sent the NDR (non-delivery report). If the NDR is getting returned to
you when sending an e-mail to someone else, you can't do anything to fix
their problem. If the NDR is your e-mail provider telling your quota
has been exceeded. You never provided a copy of the NDR e-mail and
barely described anything in it. The message, including its headers,
will tell you just who issued the NDR: their mail server or your mail
server.
