The POP3 mail server (pop.att.yahoo.com) does not support UIDL or XTND XLST,

options in the Server Settings for your mail server in the Account Settings

This typically happens if I've left the browser open for some time (over 24
hours). Email does not get downloaded until reset. If I close and restart
SeaMonkey the problem goes away.
Might it be worth creating a POP3 protocol log?

Happened again today. Log is located at:
<http://pastebin.com/JB93S115>
That's weird. I split the log into its two halves and removed irrelevant
data (i.e. fetching of the actual messages, sequence numbers, etc.) The
one remaining difference was as follows:
1738831680[7f2b66742480]: POP auth: server caps 0x21CB2, pref 0x1C00,
failed 0x0, avail caps 0x1C00
1738831680[7f2b66742480]: POP auth: server caps 0x21C82, pref 0x1C00,
failed 0x0, avail caps 0x1C00
The server caps are flags that list all of the supported functions, as
follows:
0x00002: Don't know whether server supports GURL
0x00010: Server supports UIDL
0x00020: Don't know whether server supports XTND XLST
0x00080: Don't know whether server supports TOP
0x00400: Server supports USER
0x00800: Server supports AUTH LOGIN
0x01000: Server supports AUTH PLAIN
0x20000: Server supports RESP CODES
So in the failing case, the code failed to find UIDL or XTND XLST, which
is why it threw up the dialog, but in the successful case, the code
found UIDL and didn't bother with XTND XLST.
Interestingly the code doesn't use the CAPA response to detect UIDL,
instead it assumes UIDL is available until a UIDL command fails, in
which case it assumes that it's unavailable. (There is a flag for UIDL
unknown but it is treated the same way as if it is available.) By my
reading of the code this can happen in one of two ways: 1) Connection
failure 2) Response to UIDL not starting with a +. I don't see either of
those in the log, so I'm at a loss to explain what happened there. Sorry
about that.
