Cannot login Roundcube dashboard

[TomHsiung]

Unfortunately, I encountered new issue when I tried to send email via the webmail. Note that the desktop email client of Macintosh Mail.app worked well.

This error:

Code Select Expand

SMTP Error (530): Failed to set sender "[email protected]" (5.7.0 Must issue a STARTTLS command first).

perhaps the same as this https://github.com/roundcube/roundcubemail/issues/4590? may be you need to the smtp auth settings. If its not that then when config do you have in $config['smtp_server'] and $config['smtp_port']?

[TomHsiung]

It's solved by adding to config.inc.php

Code Select Expand

$config['smtp_user'] = '%u';
$config['smtp_pass'] = '%p';

However, this raise safety concern. Is it secure to add this two lines?

What concern?

That is, would these two lines cause security flaws, or reduce the effect of TLS. Thanks.

The options have nothing to do with TLS. SMTP login is done during transaction time, after the TLS connection is established. It's a similar process to how Roundcube logins to your IMAP server.
