Our clients Email server has a maximum of 35Mb per email. If a Form created in Umbraco Forms has a multiple file uploader how can we limit the size of the email from being submitted and how can we tell the user that their email is too large? Currently we are getting this error from the Mail server: System.Net.Mail.SmtpException: Exceeded storage allocation. The server response was: 5.3.4 Message size exceeds fixed maximum message size at System.Net.Mail.DataStopCommand.CheckResponse(SmtpStatusCode statusCode, String serverResponse) at System.Net.Mail.DataStopCommand.Send(SmtpConnection conn) at System.Net.ClosableStream.Close() at System.Net.Mail.SmtpClient.Send(MailMessage message)

Thanks - but if a person uploads 10 files each at a size under the maximum upload size, for example The Max file size is 10Mb and the Email Server account has a Max Size of 35Mb, and they upload 10 files that are 8Mb would this stop this from happening? As the Total size would be 80Mb. I hope this makes sense 🙂
