[dev] SMTP settings ignored

[Sebastian Birnbach]

For the records and the archive:
Thanks Luis, you hit the spot and I got my problem fixed. There is no
warning on the console pages that the SMTP settings might be ignored.
However, all the required documentation is there in the backends.php file.
In a nutshell: several POP/IMAP servers may be defined and a dedicated SMTP
server for each of them. To use the global SMTP settings (of the console)
use something like this:

$servers['imap'] = array {
...
'smtp' => array(
        'horde_auth' => true, // use the global settings from
Settings->Horde->Mailer
    ),
...
}
