All of a sudden my Outlook Express can't send messages. I didn't
intentionally change any settings.

I use OE 6 with AOL (IMAP, not POP3).

I have discovered that if I turn OFF my firewall (Kerio Personal 2.1.5), the
outgoing message goes through.

This has only started happening in the last 24 hours.

I get the Socket Error 10053 and other error number 0x800CCC0F. Googling
that points me to my AV (AVG), but turning Kerio on and off seems to be what
gets results. Turning AVG on and off doesn't seem to make a difference. (And
AVG is NOT set to scan outgoing messages!)

I have Outlook Express configured in KPF to any protocol, any port, any
direction...

System Restore hasn't helped, either.

What's gigging?
