We have implemented a quota of 30MB of mail spool usage. This was done to keep disk usage and input/output on the mail server at a level that would facilitate good email performance for all users in Chemistry. You can link to a secure page that will tell you your current mail spool usage.

If you exceed the quota or your mail spool usage is high (e.g. 10MB+), please read our FAQ, Configuring Your Email Client for Optimal Mail Spool Usage, for advice on how to better manage your usage. (This FAQ is also accessible directly from the secure page referenced in the previous paragraph.)
