I see.  I normally have all ports closed and external checkers show the 
network as stealthed, but I had temporarily opened the IMAP port, which 
presumably drew the attention of the knockers.  It's closed again now, but I 
will need to open in when I go on holiday as I collect mail from my server.

I open the IMAP inward port - I don't think I needed the outward one when I 
used this before - and I have fail2ban on the server, which stops repeated 
attempts at guessing the password.  As far as I can see it has fully 
controlled the situation up to now.  I'm just hoping that I have enough 
control in place.

Thanks to all who answered.
