Using the March Beta, I went to register myself and got the following error (thanks for the improved error handling!):
Software error:
Can't call method "mail" on an undefined value at TWiki/Net.pm line 132.
The offending line in Net.pm is:
	 my $smtp = Net::SMTP->new( $mailhost );
At line 130:
	 my $mailhost = &TWiki::Prefs::getPreferencesValue( "MAILHOST" ) || "mail";
I don't see a MAILHOST value in my TWikiPreferences. I can't add one either since I can't register myself unless TWiki can send mail - which it can't since I don't have a MAILHOST...

It would be great if a check was made for $mailProgram in TWiki.cfg being "", which would mean "no email wanted". Alternatively, a new setting: $mail = true/false

I suspect the issue might arise because

my $smtp = Net::SMTP->new( $mailhost );
does not check that
is created properly.

Quite possibly this is because "mail" does not resolve proper on your system.

"mail" generally resolves to Outbloat on Windows machines if it can be said to resolve, let alone resolve to anything useful smile Clicking on a 'mailto' link does bring up a mail edit window with the 'to' field filled in. Don't know if an entire email msg can be "injected" and sent from a script though. Isn't there a Perl module for SMTP that would either bypass this entirely or do so if the user doesn't indicate a local mail program?

Yes, Net::SMTP. See NetSMTP.

This bug should be resolved. See MailHostBug.
