SMTP Mailserver - Settings

 

 

 

 

 

Please insert the SMTP server of your e-mail provider here. The SMTP server is your provider's outbox server, usually "mail.your-provider.com". Here is a list of some providers and their SMTP servers:


 

E-mail Server Settings

 

Use this page to set up email sending in Z-Cron. These settings apply to all areas of the program that can send emails automatically or on a scheduled basis. Z-Cron sends emails through the SMTP server of your email provider. The SMTP server is the outgoing mail server. You can get the required access data from your provider or from your administrator.

 

SMTP Server

 

Enter the name of the outgoing mail server here.

 

Examples:

 

smtp.domain.com

mail.domain.com

smtp.ionos.com

smtp.strato.com

 

Do not use the IMAP or POP3 server here. These servers are used for receiving emails, not for sending them.

 

Server Port

 

Enter the SMTP port specified by your email provider. Common ports are:

 

25

465

587

 

The correct port depends on the provider and its security settings. If your provider specifies a certain port, use exactly that value.

 

Timeout

 

The timeout defines how long Z-Cron waits for a response from the mail server while establishing the connection. The default value of 30 seconds is usually suitable.

 

SMTP AUTH

 

Enable SMTP AUTH if the mail server requires login authentication for sending emails. This is required for almost all email accounts today.

 

User

 

Enter the user name for the email account here. In many cases, this is the full email address. Example:

 

user@domain.com

 

Password

 

Enter the password for the email account here. Important: Some providers require a special app password for programs. This is especially common if two-factor authentication is enabled for the email account.

 

Sender Email

 

Enter the email address that should be used as the sender address. This address should match the SMTP account used. Many mail servers reject sending if the user account and sender address do not belong together.

 

Sender Name

 

Enter the name that should be shown to the recipient as the sender name.

 

Examples:

 

Z-Cron

Server Monitoring

Example Company Ltd.

 

 

Mail Test

 

Use Mail Test to check whether Z-Cron can send an email with the entered data.

 

Always run the Mail Test after setting up or changing the data. If the test fails, first check the SMTP server, port, user name, password and sender address.

 

Typical Causes of Problems

 

 The SMTP server was entered incorrectly.

 The port does not match the provider.

 SMTP AUTH is not enabled.

 The user name or password is incorrect.

 The provider requires an app password.

 The sender address does not match the account used.

 A firewall or security program is blocking the connection.

 

Note

 

These settings only affect sending emails. Different server data is used for receiving emails, for example IMAP or POP3.
