Why is some of my Email delayed?

Many factors contribute to the overall transit time for an e-mail message. E-mail sent to users at your domain through your account will be delivered immediately because the e-mail is delivered locally on our network. The biggest cause for delay in mail delivery is that the intended recipient’s SMTP server is unreachable. For example, if you were to send an e-mail to joe@somedomain.com, our SMTP server would first make sure that the domain name “somedomain.com” exists. If it does not, the mail is sent back to you with a “host not found” error. Next, the e-mail is sent to the SMTP server for somedomain.com. If the SMTP server is unreachable, your SMTP server will try again for anywhere from the next 4 hours to 5 days. This is the number one cause for e-mail delivery delays: problems reaching the receiving SMTP servers. Another potential cause for delay may be routing problems between our servers and “somedomain.com”. We assure our clients that once you have sent your outgoing mail through your SMTP server, it is automatically sent out for delivery. Beyond this, there is nothing we can do to speed up the delivery time for e-mail.
