Do you want to: Ask a how-to question
I am using the OnlyOffice Mail Module in our instance of OnlyOffice Workspace Enterprise. We have the Mail Module setup to use our domain using our self hosted OnlyOffice Mail Server. When trying to send an email to more than 50 email addresses I get the following mail delivery failure message:
Please, check your message recipients addresses and message format. If you are sure your message is correct, check all the **"Matthew"** account settings, and, if everything is correct, sign in to the mail service you use and confirm any verification questions, in case there are some. After then try again. In case the error persists, please read the [FAQ section](https://helpcenter.onlyoffice.com/troubleshooting/mail.aspx) to learn more about the problem. Reason: "4.5.3 Error: too many recipients"
How can I increase the mail server recipient limit for our users?
