IMAP Email not Sending

[Adam]

This message is coming up when i send a message. Is it because i am running
Norton Antivirus i have turned off outgoing email scanning and i have changed
the port to 585 and 587 and this still doesn't work . I have a mac email
address. Subject 'hi yes', Account: 'mail.mac.com', Server: 'smtp.mac.com',
Protocol: SMTP, Server Response: '556 5.1.0 Invalid From header.', Port: 587,
Secure(SSL): No, Server Error: 556, Error Number: 0x800CCC61

Who is your ISP?
Have you tried using the SMTP server settings provided by them?

Adam, I am not familiar with Mac applications, but I found the following

Try changing only the SMTP setting, and try with or without authentication
checked,
mail.optusnet.com.au

HTH?

For your Mac account, change the send settings to those specified by
your ISP. That will not affect your ability to receive emails from the Mac
account. Also, your Mac correspondents won't know (or care) that you
are sending through the Optus SMTP server.
