First appears invalid; user couldn't do anything about a misconfigured server, but can do
something about invalid characters. If something the user does could cause it and could be
fixed by the user, it seems 100% appropriate to mention it there.

Second I've fixed, adding getMessage() back and using that preferentially.

Brion: your statement is in my opinion incorrect, as this text string can also
appear for errors NOT caused by the user. You can check this by forcing your
mail system to produce an error:

On http://www.wikipage.de/de it can be seen - the mail function is not working
and you can force this on your wiki, too - that even when the user has entered a
fully correct e-mail address, s/he sees the misleading message "...Check addres
for invalid characters.". This is due to the fact that your
Specialconfirmemail.php outputs that text string in LINE 50 for _any_ error of
UserMailer() in line (which can cause that message when UserMailer() is
reporting an error).

Perhaps I should have better proposed to (better) distinguish between the
different types of errors - in the specific case mentioned here, it would be
appropriate to say "..... or potentially, check for invalid characters in the
e-mail address."

Please do me a favour and invest some minutes, as I did for reporting this
problem which was brought forward to me a user, and I investigated in this (not
related to my Enotif stuff).

In my opinion, and we are back to discussion months before, the e-mail address
should be checked for a valid form before it is tried to confirm it. See
bugzilla 959 !!

changed teh title; did not reopened that bug (in order not to make Brion angry
again.)

I propose to change the text in Language.php:

confirmemail_sendfailed = "Could not send confirmation mail due to server
misconfiguration or invalid characters in e-mail address."

Brion, is this, what you've meant ?
