EXIM4 DKIM Timestamp

Hello
The letters sent from the server using Exim 4 do not have a DKIM timestamp.
Sign date: No time included in the signature
Expiration date: No time included in the signature
DKIM is being validated.
What settings can be made to make signature timestamps appear?
Thanks.

Hi @stepan39

Add this directive to remote_smtp and remote_forwarded_smtp blocks in /etc/exim4/exim4.conf.template:

dkim_timestamps = 1209600

You can add it after dkim_strict = 0

Note: 1209600 is the number of seconds until the DKIM signature expires (in this case 14 days). This defines how long the signature remains valid after it’s created. Modify this value to suit your needs.
