Adds the settings: raw_email_max_length, raw_rejected_email_max_length, delete_rejected_email_after_days. These settings control retention of the "raw" emails logs. raw_email_max_length ensures that if we get incoming email that is huge we will truncate it removing uploads from the raw log. raw_rejected_email_max_length introduces an even more aggressive truncation for rejected incoming mail. delete_rejected_email_after_days controls how many days we will keep rejected emails for (default 90)
