This might be a really simple issue, but my searches haven’t come up with a solution yet. (only one thread where a guy said he solved it but never elaborated.)
Roundcube gives an error of "SMTP Error (250): Authentication failed.” and the log has "Must issue a STARTTLS command first."
PHP 5.6.4 Postfix 2.11.3 Roundcube 1.3.3
Things used to work just fine but it’s been a while since I’ve used roundcube to send any emails, so i haven’t noticed until now.. No self-signed certificate. Thunderbird/Apple Mail work ok.
config.inc.php has:
$config['default_host'] = 'tls://%n’; #I’ve tried ‘tls://pile.pbp.net' as well
$config['smtp_port'] = 587;
$config['smtp_user'] = '%u';
$config['smtp_pass'] = '%p’;
smtp_debug shows:

Anything else that I should check? it is a slightly older ubuntu release (15.04) at this point. I’m looking at moving webmail to another machine with a newer install.
