Rewriting FROM and TO header

Post by Admin » 02 Nov 2020, 10:08

Dear TrashMail users,

we have made a change this week-end, that we rewrite the FROM and TO headers, as more and more email services (like Outlook.com and Google Mail) are calculating a spam score which was more and more negative for TrashMail:
They check the FROM and TO header, and they check if it pass their DKIM policy validation.
If that fails, they reject forwarded emails, which could then get lost (for automatic emails).
Unfortunately this breaks S/MIME signatures. As Google Mail and Outlook are powerful email service providers (with high authority), we were forced to make this change.

I just built in a switch that you can now enable disable the FROM and TO rewriting in the web address manager in the account settings.

I just made a rollback again, as they was a problem with the database connection. I will fix that ASAP.

I fixed the bugs with the new FROM and TO rewrite and enabled again the feature.

Thanks.

The new option "Rewrite FROM and TO headers" seems to have the following effect:


When it's ON, emails have these headers:
FROM: "Sender's name" <my Trashmail email>
TO: <my real email>


When it's OFF, emails have these headers:
FROM: "Sender's name" <sender's email> via Trashmail.com
TO: <my real email>


However, the OFF behavior is different from what it USED to be (before Oct 31), which was:
FROM: "Sender's name" <sender's email> [via Trashmail.com]
TO: <my Trashmail email>

It's not a big problem now, but still, is it possible to restore this old TO field? I don't use Outlook, Hotmail, etc.

Currently it seems that no email from or via trashmail.com are delivered to Outlook at all. - Microsoft is probably blocking all emails.

After thinking this for a while. Wouldn't it be just better to provide IMAP, it would allow getting around all of these annoying forwarding problems and deliverability issues, which are being seen with the major cloud providers. Which make email deliverability almost impossible for smaller players.

Just wondering ...

IMAP/POP3 would significantly increase the storage needs.

Does this Rewriting have anything to do with me not getting my copies of the 3 emails that I sent today?

Can I assume that the recipients are not getting their emails either.
