If you look further up the thread past what was quoted, Tim
mentioned that it might be an MTU problem.
Correct, as a thing worth checking with some of the problems described.
Although, his comments about other things working may suggest it's not
the cause (or, at least, not the problem with his side of the equation;
yahoo may be up the spout).
I use IMAP within my LAN, and find it works very well. But find that
it can be a problem across the internet. If things take too long,
timeouts and failures occur. And even when things aren't that bad, it
can be quite tedious to use.
POP3 seems better over the net, it seems far less chatty. It's mostly
a continuous stream of send me messages, received it, acknowledged.
IMAP gives you a list of headers (with minimal or lots of data, your
choice), and sits there waiting for you to click on a message, then it
gets it. Delay while you read it, server falls asleep, or has to be
poked by your mail client to keep the connection alive until you read
the next one.
Yahoo keeps changing how you remotely access it. Most recently, they
insisted on encrypted connections, and that required me to experiment
with which techniques and which ports, before I got that to work.
And if they're in the middle of a hack attack, their servers may be
Personally, I found usenet (newsgroups) to be better at forums than
mailing lists, and the client software better too. There used to be a
usenet gateway to this list, I don't know if there still is. It
appears to work somewhat like IMAP (you fetch list of latest headers,
you only fetch the messages you want to look at). But the clients have
automatic culling of old messages (if you want), so you only keep say
the last couple of months cached, and they get auto-purged as time goes
on. Or, they only show your preferred age range of messages, and give
you a clutter-free view of what's available. With the latter option,
you can easily temporarily change the settings, to find an older
message. The news clients usually have better quoting than mail
clients, and it's possible to post without exposing an email address.
Another thing to consider is anti-spam systems getting in the way of
your mail traffic. If your ISP snoops on mail, especially large/bulk
mail, it may be choking.

There is no point trying to privately email me, I only get to see
the messages posted to the mailing list.
