CONFIG_TEXT: IMAP Error: Login failed for firstname.lastname@example.org from 203.0.113.2(X-Real-IP: 203.0.113.2,X-Forwarded-For: 203.0.113.2). Empty startup greeting (localhost:993) in /usr/share/psa-roundcube/program/lib/Roundcube/rcube_imap.php on line 196 (POST /roundcube/?_task=login&_action=login)
Roundcube version is 1.3 :
# rpm -qa | grep round
- Horde webmail works correctly.
The issue is caused by Roundcube restriction.
Use Horde Webmail or update php from Remi's repository.
Note: configuration of system php is a system administrative task. However, it is possible to contact Plesk Professional Services team to handle this case.
