We have added a couple of features to the 25mail.st service.
First, we now support DKIM email signing. This lets our email servers sign outgoing messages so that recipients can verify that the email was sent from an authorized server. You will need to add a DNS entry for each email domain wishing to have their emails signed. Adding a 25mail.st DKIM key will not affect other email servers you may be using. To get it setup see: https://25mail.st/faq.jsp?is_require_login=Y#dns
We have also added subaddressing. So you can invent subaddresses on the fly (e.g. email@example.com or firstname.lastname@example.org) and by default they will all arrive to that user's mailbox. For more details see https://25mail.st/faq.jsp?is_require_login=Y#subaddressing
