Emails for your domain are first attempted to be delivered to your email server. If that fails, emails are delivered and held on Dynu email servers. You can use Dynu ETRN Dequeue utility to issue ETRN command to our email server. Upon receipt of ETRN command, our email server will push emails for your domain to your email server on any specified port. This service is quite useful when your email server is not online 24x7 or if your ISP blocks port 25. This option gives you full control of email addresses of your domain since you will be able to create and delete email addresses as you wish on your own email server. This service will work with virtually all email servers. * Works with email server running on any port on your computer. This is very important if your ISP blocks port 25 inbound or outbound. * Service type may be changed to Email forward using web based email management tool. * Dequeue may be initiated via web based email management tool. This eliminates your physical presence at your email server location. * Static route for emails may be setup via web based email management tool so that neither dequeue utility nor ETRN command need to be used to have emails flow from Dynu email servers to your email server. * Web based management tool displays current number of emails in queue as well as total size of mailbox. * 24x7 phone and email based technical support. * Dequeue software included free of cost, includes Windows NT/2000/XP service version which runs in the background as a service and eliminates the need to be logged on to your computer. * Linux, unix based dequeue client software available.
