When you send e-mails from your Magento shop with no return-path set, the return-path will default to email@example.com. This e-mail address may be recognised as a spam address by spam filters, as it is a very generic email used on all Hypernodes with the same email configuration.
To avoid outgoing email being detected as spam, you should change the email return-path for your outgoing email to a valid email address (e.g. firstname.lastname@example.org) which can be managed with your own SPF settings.
If the recipient is using SAV (Sender Address Verification), and the e-mail address is not reachable, or the SPF record does not match the email source, a spamfilter could see this as a spam message.

Change Your Return-Path
Every e-mail has two senders. The first sender is the From line that is seen in the mailclient as the recipient. The other is the Return-Path. The latter address is used for errors (bounces) to control the delivery of the mail to the sender.
