Hello all,
I am not understanding what is happening on my server.
A remote server is sending email using a clients email
address. Relaying is allowed as it is a valid email address
but it is not my server!
How does this work? Anyone any ideas please? Id there
a cure?
Example
2011-11-14
Remote sender is authenticathing using correct username/password (I
suppose you use smtp auth).
So, it is enabled to send everywhere, not only to local addresses.
If it is someone who stole username/password, change password
imemdiately, and communicate new password to real customer.
Thanks Tonino,
I have done it now and am waiting to see if it stops!
Thank you for responding so quickly!
