Enter the password for user “(null)” on SMTP server “mail.thickdata.com”
I need help. I have a Mac Book Pro with OS 10.7.5
A few days ago my mail account will NOt let me send emails anymore (receiving is ok).
It give me the message
"Enter the password for user “(null)” on SMTP server “mail.thickdata.com”
My password did not change, no setting changed and all still work fine on my desk top, except my Mac Book.
Does not matter how many times I submit the correct password its not accepting it.
Any ideas, all help is greatly appreciated.
MacBook Pro, Mac OS X (10.7.5)
