Solution 2: Your Own SMTP Server: Postcast Server and Advanced SMTP Server are local SMTP server programs for Windows that let you send email messages directly from your computer to recipient mailboxes. You can use it instead of your ISP's SMTP server to increase your security an privacy. The email program you already use for sending and receiving messages can be connected to the server in a very easy way - just by using the word "localhost" instead of your current SMTP host. Having done so, you can send messages in a usual manner.

Using your own SMTP server is good for:

• Avoiding server delays. Using your own SMTP server, you can circumvent delays when your ISP’s outgoing mail server is unavailable. Most ISPs provide reliable mail service, but there are times when a mail server is down – either crashed or undergoing maintenance – and those times always seem to occur when you have an urgent message which must be delivered now. If you have your own SMTP server – provided the main Internet connection is still functioning – you can send email regardless of your ISP’s SMTP server status.
   
• Speed. When you send a message via your ISP, clicking Send merely delivers the message to the ISP’s SMTP server. Depending on its load, performance settings and other factors your mail may be sent on to its destination immediately or it may sit on the server for some time. With your own SMTP server, as soon as you click Send your message is on its way to its destination.
   
• Privacy. Anyone with access to your ISP’s mail server is in a position to inspect all mail which passes through it. Most ISPs, of course, are careful about their customers’ email security, but if you prefer to limit the vulnerability of sensitive email, having your own SMTP server cuts out a major weak point in the communications link.
   
• Control. With your own SMTP server you can stay informed of the fate of each message you send. Logs let you track each message, see if delivery was successful and, if not, exactly why it failed. While most ISPs let you know when email messages don’t reach their destination, this is not always the case.
   
• Avoiding the dreaded Relaying Denied message. You’ll see this message when you try to send email via one ISP’s server when logged on to the Internet via a second ISP. Frequently ISPs refuse to deliver mail which doesn’t originate from one of their own accounts, as many spammers try to cover their tracks by using this technique. You’re likely to run into the ‘relaying denied’ message either when you’re travelling and using a different ISP while on the road, or if you have multiple ISP accounts and you try to send mail to ISP x when connected via ISP y. With your own SMTP server, you’ll be able to send messages from anywhere in the world and through any of your mail accounts.
   
• For managing large-scale mail-outs such as newsletters, especially when your ISP frowns on bulk mail-outs of any sort.
