Email is gently delayed because Instant Access employs several anti-spam measures that require a little time to process. We use real time blacklists to block most spam. The remaining spam has been reduced by 95%. The tradeoff is gently delayed email.
Note: Before delivering email into your box, our email server asks each sending server if it sent you email. Depending upon how long it takes the sending system to reply, email might occasionally be delayed a little longer.
The overwhelming majority of email we receive is delivered to our users within 5 minutes.
