While checking outbound mailqueue (Connection>SMTP>Queues>Outbound) i found large number of mails.
See example below.

I have an urgent and very confidential business proposition for you. On the 20th of august 2008, a very rich Chinese customer of mine died with his wife in a plane crash. (Names withheld). Before his death, he confided in me and made a deposit in the sum of US$33,500,000 (Thirty Three Million, Five Hundred Thousand Dollars) in a suspense account in my bank for transfer to an account abroad. It is now over three years since their death and nobody has come forward to claim this money. The man had disclosed to me that he is the only surviving member of their family. All my attempts to trace his next of kin were all fruitless. Consequently, my proposal is that I will like you as a foreigner to stand in as the next of kin to this man so that the fruits of this man's labor will not get into the hands of some corrupt directors of the bank. You will not need to come to the bank before this transaction is concluded. I will arrange all the necessary documentations in your name which will prove that you are the next of kin. This is simple, I will like you to provide immediately your full names, address and telephone numbers so that I can prepare the necessary documents and affidavits which will put you in place as the next of kin. Upon the conclusion of this transaction, the money will be shared in the ratio of 60% for me and 40% for you. There is no risk at all as all the paperwork for this transaction will be done by me and in my capacity as the Business Manager; I guarantee the successful execution of this transaction. If you are interested, please reply immediately via the private email address:([email protected]) or fax no: + 44 20818 16677. Upon your response, I shall provide you with the relevant information to confirm the existence of this US$33,500,000 in our bank. Awaiting your urgent reply via my contact details. Thanks and regards. Mr. Robert Macaulay. Tel: +44 7831 926488
I stopped SMTP connector, then i removed the queues (C:\Program Files\MailEnable\Queues).
I can see that the incoming messages are coming from 127.0.0.1
I checked SMTP relay settings and removed the 127.0.0.1 from the “Allow privileged IP’s to relay” list.
By defauly MailEnable will allow sending out via 127.0.0.1 without any authenthication (relay). The most probably cause of this would be a compromised script on the hosted account.
