comment Should a mail server receive mail at the hostname or just the domain?
@user981178 With the exception of postmaster it is OK to refuse mail to the that domain. Many domains don't configure postmaster which makes it difficult for other administrators to inform them of issues. If you don't support postmaster you can get away with not accepting mail to its full domain name. It is usual for the mail server's host name to be different than the fully qualified domain name the the mail server uses.

See tools.ietf.org/html/rfc1537 Common DNS Data File Configuration Errors which suggest that the localhost entry is correct.

Sudo to Debian-exim, cd to /etc/exim4 and try ls -lR keys. That should give you some hints. The keys directory should have 750 permissions

Check the permissions on the directories. I set the group on the keys, an in your case the key directories to the group the that Exim runs as.,

@Krauser You have the correct transport. I took a second look at your macro definitions and updated my response. I also included a comment on split configurations.

@Krauser You can debug with a line like logwrite = ${sg....} in an acl. You can also run exim in debug mode (I do it from the command line). See the man page and specification. Check the transport (T:) in the <= lines. You could try adding a transport filter to save a copy of the outgoing message to the transport.

@Krauser Exim should log the from address in your logs. If you don't rewrite the from address, DKIM and SPF validation will not work as you expect. (I consider email from www.... to be spam.

@StefanSeidel They have provided you with a link to a site where you can get trusted. You will need to as a CNAME or TXT record to each signing domain. It is a fairly quick and painless process.

comment Why is exim not adding the DKIM header to emails?
@Krauser Yes it will pick up the whole domain. Generally you don't want to send from domains like web.xxx.example.com. Typically you would use example.com or possibly mailing.example.com. Look at rewriting the domain or setting the mailname to the desired domain, or rewriting the From and envelope domain.
