Btw, our average mailsize last we checked was 30KB. Thats a pretty good average as we're an ISP with a very wide user base. I think 4KB average is not a normal mail load.
As another OP pointed out, some ISPs apparently have to deliver a lot of spam to mailboxen to avoid FPs, bumping up that average mail size considerably. Do you accept and deliver a lot of spam to user mailboxen?
At an ISP I worked at, we did a study (just over 2 years ago) on the average size of spam mail that was been delivered to the users. It worked out to an average size of between 8KB and 10KB. This was based on data over a period of 12months with an average of a 180 million mails per month been received. Legit mail was averaging at 32KB.
I doubt whether the sizes of spam has changed much.
