When using your havilandtelco email account, our servers will allow you to send a file, or group of files, in a single email that collectively add up to a maximum of 50MB. When sending large attachments (above 15MB) it is a good idea to ensure the recipient is capable of similar email system capacity. As a practical matter, emails should be limited in size to 15MB or smaller. Sending several smaller emails when possible will help ensure delivery.
