Hi, When sending messages from clients using SMTP Auth to a server running sendmail, I'm seeing issues with SPF and Botnet thinking these messages are spam-like - I'm not sure if this issue lays with SA or with sendmail itself.
The below message is sent from a (broken) Cingular 8125 phone, hence the no RDNS.
