Please verify your account is not suspended. Individual users can verify their account status using the Kolab Now Cockpit. Users of group manager accounts (custom domains) will need to contact their account administrator.

Kolab Now uses various anti-spam measures that block consumer Internet lines and server systems with bad reputations from submitting email to Kolab Now customers. These restrictions are applied on the inbound SMTP servers used by third parties to deliver email messages to our users, but not the SMTP servers our users use to submit email messages.

You may have used the wrong configuration for your client application. Please ensure that you are using the following settings for your client:

SMTP Server Addresssmtp.kolabnow.com
SMTP Server Port587
Security SettingSTARTTLS
