Thank you for pointing this out. I am no way expert but trying to study and understand. I then found other negative comments regarding the lack of DMARC, while on posteo website they say: “We have a DMARC “none” policy for Posteo email domain names, since DMARC is currently not recommended for mailbox providers. Outbound DMARC policies are primarily “best-suited for transactional emails and semi-transactional emails” (dmarc-org FAQ). At the present, DMARC has implications which do not meet customers’ individual use of email.” link

The dmarc-org FAQ is interesting too. I understand that Posteo publishes thier DMARC record, if I am not wrong

I would appreciate your opinion, you seem competent! Thank you

Thank you, very useful. For some reason Posteo is not on the list

Thank you @[email protected]

Thank you. If I have not confused the different email proveiders, with mailbox encryption in transit is always active, while it needs to be activated while at rest. I do not understand why someone would not want their emails to be encrypted even at rest, by the way.

Thank you. I had come across KolabNow, I will look into it again. I have never used PGP and it does not seem a smooth mechanism to me, as I am used to encrypt emails with password. Maybe I am wrong … PS: I am onWindows

Thank you. True. I did not know that FairEmail supports, optionally, PGP! Is that an easy process to be set-up? I have never used PGP and it does not seem a smooth mechanism to me, but maybe I am wrong ?
