sorry for delay to reply to the topic..
I have the always_bcc in the main.cf, there is an
out@domain.com and as you know it will catch all the outbound traffic, I checked the
out@domain.com and I founded that there are too many messages from
myaccount@domain.com to
someaccount@hotmail.com or from
admin@domain.com to
user@yahoo.com or
support@domain.com to
another@gmail.com, so is there anything must I do to trace and stop this kind of messages?
