What is the maximum attachment size I can send or receive with Supanet email?
Supanet has recently increased the maximum attachment size you can send and receive. The maximum file size you can receive has been increased to 5MB. There is no specific size limit for sending files. However, we do impose a 50MB ceiling when sending. For example, 2MB to a total of 25 recipients or 10MB to a total of 5 recipients. The total amount of data sent can never exceed 50MB. However, in practice, any attachment over 3-3.5MB could cause problems for your mail handler which could time out before the attachment has been sent. In the unlikely event that you still find the limits insufficient, we suggest you compress the file with a utility like WinZip or UltimateZip or send as separate files if possible.
