all, I've been using Entourage to access my .mac account for quite some time. All of a sudden, about 2-3 weeks ago, I was unable to send. I can recieve all mail into Entourage just fine, but no sending. I get an error message: Mail could not be sent using the account .mac, error:-23016. I have found this error number on various sites, but with no resolution. I have verified the username and p/w in the SMTP settings, I have tried SMTP server requires authentication both checked and unchecked, I have checked and unchecked the "Override default SMTP port" box, and I have even created a second account from scratch, but with the same result. HELP!!!
