When you send a report by email, Webroster immediately tells you whether it has been sent successfully. If no error message appears, the system has sent the email correctly.
In this case, your email server may be blocking the message, so you need to contact your IT department to check your email security settings.
A common cause of this issue is a limit on the number of SMTP messages allowed per session. If this applies to you, contact your SMTP (email) provider and ask them to increase the limit.
