jlivingood posted : NormanS is correct that the DNS servers are located in our regional POPs. This typically provides a "better" answer for CDN content than any off-network DNS (though I concede that some of these have interesting features and that makes it a worthwhile trade-off for some users).

Use OpenDNS, Besides faster DNS Servers (so they say) ...

I have never been able to demonstrate that OpenDNS has better performance than my ISP's DNS servers:

C:\utils\ns_bench>ns_bench 68.94.156.1 68.94.157.1 4.2.2.1 4.2.2.6 208.67.222.222 208.67.220.220Nameserver              Response Time (ms)                        min/avg/max/stdev/retries 68.94.156.1             11.48/17.70/29.60/7.56/068.94.157.1             11.74/20.26/29.76/6.13/04.2.2.1                 22.33/26.10/37.59/5.78/04.2.2.6                 22.57/27.84/38.81/6.23/0208.67.222.222          13.43/16.44/27.45/5.51/0208.67.220.220          12.92/18.44/29.61/6.73/0

Of course, my ISP (ATTIS) locates their DNS servers in the POP center, so DNS request don't have to leave their transit network, then return. I think Comcast DNS servers work in a similar fashion (except for the 'Anycast' aspect of operation).

Think I've figured it out -- for some reason, my router isn't pulling the DNS servers when it gets the DHCP address assigned. With those entered manually, things are working.

Any idea why that would happen? I recall having this problem before . . .

(this is on my mom's computer/LAN, which I try to keep running when I visit).

Linksys BRFS41 router, if that matters

Does Comcast block this or is something funky with the router at my mom's house?

No, Comcast does not block IMAP. I'd look @ LAN-related issues, as you mention.
