Client SMTP Settings
By Jeroen van Meeuwen on September 16, 2017
When setting up a client for submission use the following settings:
SMTP Settings with implicit TLS
| Setting Name | Value |
| Server Address | smtp.kolabnow.com |
| Port Number | 465 |
| SSL/TLS (aka. Encryption or Security) | SSL/TLS |
| Authentication | Automatic or Normal Password |
| Username | Your Primary Email Address |
Please note, that even when your primary email address is not @kolabnow.com, but is e.g. @mykolab.com or @myprivatedomain.org, you have to connect to the server: smtp.kolabnow.com.
SMTP Settings with explicit TLS
In some clients and in some network configurations it is not possible to use the implicit TLS. In such situations it is possible to use explicit TLS – Also known as STARTTLS. This workaround is offered as exactly that: a workaround. It is discouraged by Kolab Now and should be temporary.
| Setting Name | Value |
| Server Address | smtp.kolabnow.com |
| Port Number | 587 |
| SSL/TLS (aka. Encryption or Security) | STARTTLS |
| Authentication | Automatic or Normal Password |
| Username | Your Primary Email Address |
