Ubdate debian 10 to debian 11 exim4 not working

1

I just upgraded from debian10 to debian 11 and everything works fine except exim4 which doesn’t let me receive emails, it gives the following error

failed to expand “${extract{1}{:}{${lookup{$local_part@$domain}lsearch{/etc/exim4/domains/$domain/aliases}}}}”: NULL

How can I solve this problem? Thanks

Search function… Exim4 broken after Debian 11 upgrade - Tainted filename / temporarily rejected RCPT

perfect, I put the new exim4 file and now everything works again

of the other services apparently everything is going well. Do I have to look at replacing the configuration files with new versions or does this update only affect exim4?

Doing a test I see that now it gives the following warning, is it something new from the exim4 configuration for debian 11?:

SendSMTPCommand: Timeout waiting for response after 15 seconds.

Any custom changes will be lost if you replace the exim config file.
