No problem (has to be craft beer ;) ),
I still wonder if it is the transport that it is being used, it could be different from when you are sending on the command line. When I had to do something like this with a mailman list server the default smarthost transport needed adding to for it to attach the DKIM header.
For debugging, exim -bh <ip address connecting to the mailserver> , it is a fake smtp session. I would only do the following if it is a test box as it won't run if port 25 is already bound to, exim -bd -d+all 2>&1 | tee /path/of/output_file (it will sit there waiting for a connection), you can get the output to the terminal and saved to a file to search afterwards. It does provide alot of useful information as it shows all the acl's, routers and transports etc that it runs through during the smtp transaction and you can see when it doesn't do what you are expecting. The Exim man page is well written and does have lots of helpful information (man exim) that has pointed me in the right direction previously.
I'd also check /var/lib/exim4/config.autogenerated to confirm (at the top it confirms if it is split or non split) so you know if you are putting any changes in the correct locations.
I'm guessing this is a production box, whenever I'm trying to debug something like this I use a test box and use the brilliant swaks to send mail to it, if you are running Debian on the system you are sending a message to it apt install swaks.
This is an Exim issue, you might find more help asking upstream on the Debian mailing lists.
Hope this helps a little bit.
Thanks

But I am adding the DKMI signature headers on this email server...
I don't know why sendmail used on dovecot send the mail to exim2 -DOUTGOING all software on the server is using exim1
because if I use my sendmail on command line from the user the email allways take the headers of DKMI.. but if I use dovecot command line
sendmail_path = /usr/sbin/sendmail
don't send the email with headers..
In order to debug the issue I create a warper /programas/scripts/eximvacation/eximwarper to get a log about the comand line :-P if you have any idea will be great!
Thanks to answer!! :-D beer on Spain granted.

Hi ,
I believe you'll need to add to the relevant Exim transport that you are using. For example if you are a smart host add it to the transport for that. Example that might help:

Hi to all I was using dovecot like 15 years on multiples debian places, and I have the same issue on debian 12 and debian 11. on my configuration I use exim with 2 process to send email, and at the same time use mailscanner to scan all the email that runs on the server. exim1 get the email, and put on the mailscanner directory and mailscanner scan the email and put on another directory to be send by exim2...

The mail issue here is with the norms for spam from google the nobody get the vacations emails reply. as far I see on the logs of sendmail I see only the email on the exim4 -DOutgoing (log) (I don't know why) because if I send the mail using send mail go to the whole process I don't know why dovecot send the mail to exim -DOUTGOING and not use sendmail on command line.. There any way to create a warper to capture the mail and sending "like this one" /usr/local/bin/dovecot-sendmail-wrapper I enable the debugn on send mail to see what is doing dovect but no luck Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim: Created Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim: Establishing connection Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim: Forked child process Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim (870409): Connected to program Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim (870409): Finished streaming payload to program Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim (870409): Finished input to program Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim (870409): Disconnected Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim (870409): Waiting for program to finish after 0 msecs (timeout = 30000 msecs) Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim (870409): Child process ended Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim (870409): Destroy Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: sieve: msgid=2118db23-b529-4b96-8d36-4a9ed7596a03@pk25.com: vacation action: sent vacation response to ediaz@pk25.com I include a example: This is the mail headers sent using dovecot sendmail
