imsp[934]: imsp exiting: accept (0x4809a8ac): Software caused connection abort.
This possibly related cause was found via Google:
"'Software caused connection abort'. The Berkeley definition is something like: 'A connection abort was caused internal to your host machine. The software caused a connection abort because there is no space on the socket's queue and the socket cannot receive further connections."
The imspd is installed with the imsp-ia add-on, which allows it to authenticate to the IMAP server, in case that tells you anything.
Any thoughts?
Thanks, Ted Fines Macalester College
