HELP! can receive email, but cant send--possible virus?
Posted on 2006-04-27
Wednesday we started receiving these emails we never received beofre from different addresses with the same content about some business opportunity. everyone in our company received them. Now today we can receive email, but we cant send to certain of our big customers (who I know have very good security). We can recieve from them but we cant send. Our emials come back and say "Body of message generated response: 550 5.7.1 reject: message blocked" I think we may have goten a virus that was sending emails out, but I dont know what to do. Our antivirus software hasnt reported anything, and I am ata loss. Can anyone help?
