Don't thinks it’s a Firewall, as its not happening all of the time. However not something I have considered before.

Negative, wireless is turned off. Does your ICON work all of the time? Do you use outlook?

Yes its
xyz@stormforce.biz My web hosting company suggested the same, I changed port to 5?? Can’t remember what the second 2 digits were (585 rings a bell!), but changed back to 25 after it did not help. Will try your 587 anyway.
Having done some web searching on this topic is appears I am not the only ICON 255 user with this problem, seems there are many users who can not send mail through outlook.
