Title: S/MIME signed message rejected by SMTP: Error: bare<LF>received
Post by: afget6498 on May 15, 2024, 09:26:56 pm

Since a few weeks I use a S/MIME Certificate with my posteo.de Account. I bought the certificate through posteo. see their blog.

I installed the certificate in Thunderbird (works well) and AquaMail Pro 1.51.1-461 on a Pixel 6a (Android 14, latest update).
First it worked to sign emails on Thunderbird and Aquamail, but recently my signed Emails are rejected by the Posteo-SMTP with following message:

521 5.5.2 submission01.posteo.de Error: bare<LF>received

Posteo support tells me that the signed messages are not properly formated and they reject for security reasons.

What can be done to solve this issue?
