Smartermail log interpretation

Question asked by Conner - 5/12/2019 at 4:39 PM

Hi,

I use a custom log post-processor to strip out pieces of useful information and have a question about something in the SMTP log. I see a number of examples similar to:

senderEmail(1): fjran6vcao6if569nr1t1wrg6igj2tt3-b@enews.monogramonline.com parsed using: <fjran6vcao6if569nr1t1wrg6igj2tt3-b@enews.monogramonline.com>
senderEmail(2): monogramonline@enews.monogramonline.com parsed using: =?UTF-8?Q?Monogram=20Online?= <monogramonline@enews.monogramonline.com>

Many incoming emails have only one line with the 'parsed using:' phrase in it, but many have more than one. Can someone shed light on the difference between the two and what they indicate?

Thanks!

--Ben

Ben, I believe what you're seeing here is a byproduct of SRS (Sender Rewrite Scheme) adjusting the from address to account for the forwarding it has undergone:

https://en.wikipedia.org/wiki/Sender_Rewriting_Scheme

Do you have SRS enabled under Settings>Antispam>Options? The toggle you're looking for here is the Enable SRS when forwarding messages setting. More information about this setting from our help is found here:

Enable SRS when forwarding messages - Enable this to allow the mail server to re-email (as opposed to "forward") an email message so that it passes any SPF checks on the recipient's end.

Hi Kyle,

Thanks for replying. Wasn't aware of that and no, I don't have that enabled.

If my intent is to find the email address of the original sender and I encounter something like this, would a reasonable approach be just to take the first one I find?
