Gmail virus blocking (Score 1)

Just tested with the harmless Eicar virus. Here's what I get from our sending mail server (various bits XXX'd out) Cmd: EHLO - xxx.xxx.xxx.com Res: 250-mx.gmail.com+at+your+service Cmd: FROM:+SIZE=5940 Res: 250+2.1.0+OK Cmd: RCPT - TO: Res: 250+2.1.5+OK Cmd: DATA Res: 354+Go+ahead Res: 552+5.7.0+Illegal+Attachment+g9si301327wra It's obvious that the e-mail is blocked at SMTP level - the mail never gets to my Gmail account and I never know if it came in. Let's hope that there are no false positives because I'd never know!!!
