I do all configs but it still did'nt works. I have no ca cert in my folders.
# The full hostname
hostname=***************@gmail.com
# Are users allowed to set their own From: address?
# YES - Allow the user to specify their own From: address
# NO - Use the system generated From: address
FromLineOverride=YES
UseSTARTTLS=YES
UseTLS=YES
AuthUser=************@gmail.com
AuthPass=*************
I Solved it by changing hostname to localhost.
