2 ways Fixed SMTP Error (435): Authentication failed directadmin

Authentication failed directadmin

Tình trạng lỗi thường gặp,

While sending an email from Roundcube webmail I was receiving following error

[error]SMTP Error (435): Authentication failed [/error]

1/ To fix this issue edit file  /usr/local/cpanel/base/3rdparty/roundcube/config/main.inc.php

and make following changes. i.e remove %u

$rcmail_config[‘smtp_user’] = ‘%u’;
$rcmail_config[‘smtp_user’] = ‘ ‘;

2/ Try resetting your password, that sometimes helps.

If you have any ways better please comment below
