A while ago I went through the RFC's to look for ones of particular interest to postmasters. This list is by no means exhaustive and by no means complete, but I keep them on my site so that they can be searched in conjunction with the official documentation, specs and guides various people have written. These might be worth a look for anyone interested in host names and misc DNS behavior in general. RFC 1912 - Common DNS Operational and Configuration Errors http://www.exim-new-users.co.uk/content/view/198/39/ RFC 4343 - Domain Name System (DNS) Case Insensitivity Clarification http://www.exim-new-users.co.uk/content/view/195/39/ RFC 4367 - What's in a Name: False Assumptions about DNS Names http://www.exim-new-users.co.uk/content/view/191/39/ RFC 4697 - Observed DNS Resolution Misbehavior http://www.exim-new-users.co.uk/content/view/192/39/ Feel free to suggest one if it's not listed here: http://www.exim-new-users.co.uk/content/blogcategory/25/35/ Thanks Jason_Meers -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
