Think I've sussed it, I changed the outgoing server settings from STARTTLS to SSL/TLS and everything is working now, can't understand why the two devices need different settings but sometimes you have to accept small wins without knowing how you won, lol.
I'm going to try the same settings on the phone to see if it works with the same settings. Peter --------------- Sent from my Android phone with K-9 Mail.
