Unable to send mail via web interface after roundcube update
Open, Needs TriagePublic


This is likely related to the recent roundcube updates but I never tried sending until read mail was fixed.

# dpkg -l roundcubemail
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)

I thought I had carried all my old config options forward during the update but I am getting SMTP authentication errors when I try and send mail from the web interface.

From roundcube/errors.log

and from roundcube/smtp.log:

$config['smtp_server'] = 'tls://%n';

// SMTP port. Use 25 for cleartext, 465 for Implicit TLS, or 587 for STARTTLS (default)
$config['smtp_port'] = 587;

// SMTP username (if required) if you use %u as the username Roundcube
// will use the current username for login
$config['smtp_user'] = '%u';

// SMTP password (if required) if you use %p as the password Roundcube
// will use the current user's password for login
$config['smtp_pass'] = '%p';

Sending email from an SMTP client (tried both K9 Mail and postfix relay) works fine.
