comment Workarounds for maximum DNS-Interactive terms limit exceeded in SPF record?
@JeffAtwood Normally DKIM is is signed by the sending domaim. If you use a subdomain, then sign with the sub-domain. However, it is legimiate to sign for a subdomain, but may not get the processing. DKIM records need to be created relative to the signing domain. It is also common for the originator to sign the document to allow origin verification.

@JeremyWarne Second link looks like the fix, if it isn't a spambot on your server.

comment Exim - password disclosure by world-readable exim.conf - is that necessary?
@sa289 Yes, however root always has access. The only time exim should need passwords is when it is running as the user it is programmed to use when processing message for or from its queue.

comment Exim - password disclosure by world-readable exim.conf - is that necessary?
@sa289 Users are less likely to invoke exim than programs they use. One well defined method of delivering email is to invoke sendmail (exim is symlinked) and use it to start the message on its way. Programs like mail and mailx typically use the sendmail interface to deliver mail.

comment Exim - password disclosure by world-readable exim.conf - is that necessary?
@sa289 Your password is used in an authenticator block, but it should not be defined there. It should be in one of the password files: /etc/exim/passwd or /etc/exim/passwd.client. The password files should be appropriately secured. Ubuntu/Debian leaves the generated configuration file with 644 access, which agrees with my understanding that it may need to be run using almost anyone's privileges.
