I have succeeded randomly with the above. I know that is not best
style of programming (too nicely said) and I do read documentation but
I do not read enough.

Before sending email I have read documentation and I searching similar
example to what I was thinking should be similar. And did not finish
searching examples. Most similar example was for accounts set in
jabber.el XMPP chat client.

Is there a way to make sure that field is not empty?
