The amount of spam and virus emails being sent over the internet is not new, but seems to have been having more of an impact as of late. Due to the nature of our mail forwarding service, this sometimes leads to ISPs and free email services being forwarded a large number of “junk” email. In the past, easyDNS has always strived to limit the amount of filtering that has been imposed upon the mail forwarding service that we provide. Unfortunately, in the case of Videotron, we have been reluctantly forced to subject all forwarded email destined for Videotron email addresses to “greylisting”, and not just the catch-all mailmaps as announced recently. More information about greylisting can be found here, at the following URL:

In short, greylisting is a method where a piece of email being relayed to one of our mailservers is initially deferred. This means that it is not accepted upon the first attempt, rather, the sending mailserver is told to relay it again at a later time. With standard mailserver configurations, such as those generally maintained by your ISP and free email service provider, the email will be re-sent at a later time, usually anywhere from 5-20 minutes. For spammers and machines sending virus emails, they generally don’t operate like standard mailservers, and usually won’t relay their email again at a later time. Right there, at least 50% of spam and virus emails have been effectively stopped.
Unfortunately, with greylisting enabled for all email destined for Videotron email addresses, this means that those emails will be subjected to a delay every time they are handled by easyDNS mailservers. This has been put into place to limit the amount of blocking that we have endured by Videotron. The idea is that it is better to have email relayed a little late, than not at all.

[Additional clarification: It is important to know that greylisting introduces a delay for the first message received from each remote mail server, but not for subsequent emails from that same server once the server has passed the greylist challenge. Once a given server has passed the greylist authentication, subsequent email from that server are relayed at normal speeds.]
We apologise for any inconvenience caused by this implementation.
