Outgoing Mail Configuration

If your WorkBook is hosted by WorkBook Software this page is mostly irrelevant.


Sending mails from WorkBook is a very common task, but before this works some configuration is required.

WorkBook can send a large variety of mails including Time registration reminders, overdue invoices, personal communication with suppliers, etc.


Outgoing mails are sent from WorkBook using SMTP (Simple Mail Transfer Protocol). This allows WorkBook to communicate with most mail servers.

NOTE: In order to send mails from WorkBook, system variable 1148 must be enabled


    • Address to the mail servers SMTP port
    • Find out if the SMTP port uses plain or explicit SSL/TLS for communication
    • Anonymous authentication for relaying or a username and password combination*
    • An email address used for sending out automatically generated emails

*These authentication methods are supported for username and password:

    • LOGIN (Plain text)

The following system variables are used to control which SMTP server is used by WorkBook for sending mails:

Id Name Description
262    SMTP server name or IP number This is the IP address or domain name used by the mail server for receiving SMTP communication for outbound mails
641    SMTP port number This is the port used to receive SMTP communication, the default for plain communication is 25 and 587 for SSL/TLS
642    Use SSL for SMTP If the SMTP server expects explicit SSL/TLS, this will most often be the case if port 587 is used
643    SMTP Username The username required for authentication. Most often a mail server accepts the full email address as username, example: something@mydomain.tld
644    SMTP Password The password required for authentication
646    Use SMTP Login Whenever the username and password specified here should be send to the server. If this is disabled WorkBook will attempt to send the mail without authenticating

Common Configurations

If your organization is using one of the following providers, these are the settings required.
By default none of these configurations will allow your users to send as themselves, and therefor its recommend you enable system variable: (760) Force the use of email address from Agent sender.

Id Name Office 365 Google Apps
262 SMTP server name or IP number smtp.office365.com smtp.gmail.com
641 SMTP port number 587 587
642 Use SSL for SMTP True / Checked True / Checked
643 SMTP Username <username>@<domain>.<tld> <username>@<domain>.<tld>
644 SMTP Password <Password> <Password>
646 Use SMTP Login True / Checked True / Checked

Mail addresses used

WorkBook needs an email address for sending automatically generated emails. Some mails are sent without any user interaction like Time Registration Reminders.
This email address can also be used to send all outgoing mails (because some servers does not support sending on behalf of other users)

The email address is controlled by the following system variables:

Id Name Description
289 “From” email address This is the mail address that WorkBook uses when sending notifications and other automated emails, it is recommend that it matches the mail address of your SMTP Server.The mail address can also be used as a forced sender, so all mails send from your employees is send using this mail address, but with a “Reply To” field pointing to the employee email.
290 Agent default “From” name This is the mail displayed in the mailbox every time an automated mail is send using the: “From” email address.
760 Force the use of email address from Agent sender This system variables forces all outgoing mails to be send using the address from the system variable: “From” email address as stated in system variable 289.
Check your mail servers configuration to see if this is required. By default, both Office 365, Google Apps and Exchange Server requires this setting to function.
None None In a few rare cases the sender email for Agents are configured in the Agent Parameters.

Domain Verification

To send emails from WorkBook,you must also verify your domains in WorkBook. In hosted WorkBooks, there is already a domain configured by default.

See the following guide on the subject.

Checking that the mail settings are correct

The easiest way to check that the new settings are correct and working, is by sending an new email using the mail dialog to yourself.


The troubleshooting steps below are only suggestions and may not be full solutions.
Most of the headlines are partial matches of the error message.

No such host is known

Check system variable: (262) SMTP server name or IP number, the server is unable to resolve the DNS name you entered.
You may try and diagnose your DNS name issue using mxtoolbox.

A connection attempt failed because the connected party did not properly respond

This indicates connection issues to the IP Address used by your mail server, please make sure the IP Address or DNS Name is correct.

No connection could be made because the target machine actively refused it

This error indicates that the SMTP Server address is correct, but we are unable to connect to the SMTP Port.
Common causes is, firewall, wrong port number, or the SMTP Service is stopped.

BDAT command has been rejected by the server

This tells you that the sender email address has not been granted access to send mails from your server. You can choose to grant access to the mail address in question, or you can force the sending of mails with a default sender.
If you mark the checkbox in setting 760 in your system variables, the sender of mails will be changed to the value stated in system variable 290.

Mails are marked as spam

There can be multiple reason for this, start by checking your SPF and DKIM configuration.

If these mails are for internal users, consider white listing the emails. (Office365)

A user attempted to send an email from a non-verified domain
