This problem falls under what I mentioned as
"b) you are sending from home but using an SMTP server
other than the one supplied by your ISP".
Your ISP, Comcast, will not let you use a port 25 SMTP server
other than the one supplied by Comcast.
The workaround is as follows:
Go to Tools, Accounts, select the mail.candXXXXkites.com account,
Properties, Servers. For the outgoing (SMTP) server change the
name from mail.candXXXXkites.com to smtp.comcast.net.
Do not change anything else. Try sending.
Your correspondents will not notice that you are using a
different SMTP server.
