Restarting the Postfix Server
A popular option for relaying security headers, security classification and subject lines is to directly connect to a local computer and create a local SMTP server program. With this option, recipients can receive and e-mail messages from your computer and your PC. Using an out-of-the-box server solution is still the most common way of sending unsolicited emails, but a more robust option is to use a program that offers built-in functionality for filtering, forwarding and scheduling options. You can also use a program that works seamlessly with Outlook and other programs such as Gmail, Yahoo or MSN. An advantage of using a program such as this is being able to use a local smtp server for both sending and receiving emails between employees and clients.
Some administrators find that there are problems with using a standard inbound smtp server to handle the mails. The main problem is that it is unable to establish or communicate with the recipient. Since MS Exchange performs all of the necessary protocols to make sure the emails arrive correctly, administrators have no option but to run the inbound process within the exchange server to ensure the emails get to the intended recipient. This can be problematic because while the service is running, other services on the network could be experiencing problems, which could hinder the performance of other mail services. If you're unable to run the local server email client in Windows until the network administrator restarts the postfix server, then you'll have an additional problem because any attempts to send or receive emails will fail.
