thanks, there goes one of the assumptions for my special antiviral
trick. This applies just to accounts that are publicised on usenet.
These tend to attract virus, and virus tend to pass through RCPT time
antispam measures.
One of the antiviral measures presumes that the peer will connect
using esmtp, and give the message size at MAIL FROM:. If the message
size is larger than, say, 15KB, the message is rejected. Thanks to
yahoo, I have no way to do that with virus sent via their servers.
