This article outlines the necessary settings for any generic IMAP client.
Note that most regular clients will use Automatic Configuration and Discovery when originally setting up the account. However, when account settings need to be verified or changed, this article outlines the desired configuration for generic IMAP clients.
IMAP Settings
Receiving Email:
| Setting Name | Value |
| Server Address | imap.kolabnow.com |
| Port Number | 993 |
| SSL/TLS (aka. Encryption or Security) | SSL/TLS |
| Authentication | Automatic or Normal Password |
| Username | Your Primary Email Address |
Sending mail:
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 servers: imap.kolabnow.com and smtp.kolabnow.com.
SMTP Settings with explicit TLS
In some clients 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.
