ITNT MAIL SPOOLING

 

ITNT offers a mail spooling service for hosts that do not have a full time connection or as a backup email solution in the event of your mail exchange server going offline. Emails coming to yourdomain.com will be queued in our mail server. If your mail server has an intermittent Internet connection then the mail server in your corporate LAN connects to our server to de-queue the mails. Common PC LAN GroupWare Applications like Novell GroupWise and Microsoft Exchange support ETRN for mail retrieval. The ETRN command is an extended Simple Mail Transfer Protocol (SMTP) e-mail de-queuing command that is issued to an e-mail host for Internet e-mail retrieval. Otherwise, our server will automatically send all queued mail to your server when it becomes available.

 

To ensure that your e-mail is free from viruses and spam, we protect your mailbox with anti-spam and anti-virus software. You can therefore receive e-mails without having to worry about downloading a computer virus or have your staff members receiving unwanted spam.
