I am using Outlook Express and I was trying to send out a suspisious file that only VBA32 detected it heuristically. The message could not be sent because its size exceeded the server's limit. You can use the option, located in Tools | Accounts | Properties | Advanced, to break messages into smaller parts. Subject 'Suspected homemade virus/trojan/keylogger', Account: 'CyberMew', Server: 'smtp.gmail.com', Protocol: SMTP, Server Response: '552 5.7.0 Illegal Attachment d16sm1986475wra', Port: 465, Secure(SSL): Yes, Server Error: 552, Error Number: 0x800CCC6D This is a report processed by VirusTotal on 08/17/2005 at 11:56:50 (CET) after scanning the file "ionduper04b.zip" file.
