comment the name of name server
@MadHatter The resolver will contain IP addresses of the local name servers which may or may not be published as nameservers for the local domain. In NS records they are always specified by name, although they may be specified by a short name such as NS1 if they belong to the domain.

comment DMARC is blocking email that seems like it should be allowed
adkim=r is the default and allows subdomains in the from address. I don't see any mechanism for disabling either SPF or DKIM validation of the from address. Enabling reporting provides detail on why things failed. I have found major carriers email reports daily.

comment Where to find the default status codes file for Apache in Ubuntu 12.04
@moderns Add the ErrorDocument specification for each error code you want to your configuration. You will need one for 414. Verify the file in sites-available is the one linked to sites-enabled. I'm past may experience as I don't encounter 414 errors. Just remember to specify the URL path not the file path.

@RossHodgman You should always use a relay for you laptop. Your IP is likely listed in the PBL because it is dynamic and therefore cannot be reliably reached to send status messages or send replies. Well over 90% of the spam I receive comes from servers which don't have the a static IP address and the requisite rDNS entries. Please do NOT try to emulate them. Use your providers relay.

@moderns It looks like you want to use your own pages, so just do so. I provided an example in the latest update. At that point it becomes more of a programming issue than an Apache issue.
