Hi,
I cannot send emails from the Webmail client.
In the logfile /var/log/maillog I find this information:
Dec 3 21:04:30 vm101-nethserver postfix/pickup[19968]: 2188D3A76: uid=48 from=<user@mydomain.de>

The FAQ in SPAMHAUS provides this information:
PBL listings do not prevent you sending email unless your email program is not authenticating properly when it connects to your ISP or to your company's mail server. This can happen if you have forgotten to turn on 'SMTP Authentication' or if you have switched 'SMTP Authentication' off by mistake.
This drives me to the following question:
How can I verify if SMTP authentication is turned on?
How can I ensure that emails sent from Webmail client have SMTP authentication turned on?
