comment Getting My “Foot in the Door”
installation work is good, it gets you familiar with the equipment, standards and especially layer 1, which can be VERY important in troubleshooting issues later. I can't tell you how many brilliant techs fail to solve certain problems because they don't even consider wiring as an issue.

It may take some time for the changes to propagate. Some hosts can take 24-48 hours, some will have it updated in 4-6 hours.

They are faster (1 query vs 2 queries). It is especially useless when you are just looking at the same server, CNAMEs are best for pointing to a server outside your domain, see this article: rscott.org/dns/cname.html

comment SPF help; My emails are still considered spam
Since RDNS is setup, you now need to check central blacklists, which most major ISPs will reference, you can check common blacklists using this tool: mxtoolbox.com/blacklists.aspx. It would also help to know exactly what the bounce error message is saying (error codes and all).

comment SPF help; My emails are still considered spam
I see a txt and a couple of A records, just no PTR record. If you do a host command on your IP, does it return your domain?

comment Switching to IPv6 implies dropping NAT. Is that a good thing?
Exactly, get a real router and you won't have to worry. SonicWall has some excellent options to provide the security you need and will support IPv6 without a problem. This option will probably offer better security and performance than what you currently have. (news.sonicwall.com/index.php?s=43&item=1022) As you can see in this article, you can also do ipv4 to ipv6 translation with sonicwall devices for those that can't handle ipv6.

comment When analyzing packets with Wireshark, is there a way to know which program is sending which packet?
You don't need one, it is just a simple method for seeing what app is sending info out to which IP address. It will of course only give you basic information, so it all depends on what level of detail you're after.
