What technology is used by the best email forwarding service?

For the tech guys! The Sender Rewriting Scheme (SRS) is a solution for the @Emailforward. mx servers responsible for forwarding. It helps to modify the sender’s email address and keep it associated with the message at the same time so that email is successfully delivered to the destination mailbox without breaking the SPF record.

Email forwarding is handy beyond a doubt. But in the intervening years since email forwarding came along, Sender Policy Framework (SPF) was also created.

That’s a system wherein you use your DNS settings to specify which email servers are allowed to originate email from your domain, and yes, you can publish SPF records for your domains in your DNS settings here Professional email forwarding.

But if the person sending you an email has SPF enabled on their domain, and you are forwarding that email to another destination that is enforcing SPF validation, then that would break SPF validation, and either reject that message or possibly mark it spam (depending on how the sender has their SPF data set up).

SPF is an email authentication protocol that allows the owner of a domain to specify which mail servers they use to send mail from that domain. Brands sending emails to publish SPF records in the Domain Name System (DNS). These records list which IP addresses are authorized to send an email on behalf of their domains Email custom domain.

During an SPF check, email providers verify the SPF record by looking up the domain name listed in the “envelope from” address in the DNS. If the IP address sending email on behalf of the “envelope from” domain isn’t listed in that SPF record, the message fails SPF authentication.

Sender Rewrite Scheme (SRS) was created along with SPF to fix that problem.

When you want to use email forwarding, SRS will rewrite the envelope in a way that will

1. preserve the identity of the sender for replies

2. pass any SPF validation

It does this by specially encoding the “From” envelope sender using an intermediary domain dedicated for the purpose.

Only a few email forwarding services support SRS, but it comes standard on all @Emailforward. mx mail forwarding.

Conclusion

I’m personally a big fan of @Emailforward. mx. You never have to worry about missing important emails or managing multiple email accounts. However, you need to weigh the downsides and ensure you find an email forwarding provider that offers the best service and that have implemented the right technology to ensure the email arrives at the destination and this exactly what they achieved @Emailforward. mx
