I have read about needing to use IMAP rather than POP for the
incoming mail server so when I created the profile I selected IMAP,
rather than the usual POP.

For the incoming mail server I have typed
"mail.stirlingnarrowboats.co.uk" (this is the info given by the
hosting company)
For the outgoing server I have typed "imap.aol.com"

For an IMAP account, imap.aol.com would be the incoming server. You could
certainly use mail.stirlingnarrowboats.co.uk as an outgoing server (it it
accepts SMTP) or as an incoming server for a POP account. You appear to
have specified things backward.
