What is the maximum size of email, including attachments, I can send or receive?
A. 10MB. Any email including attachments larger than 10MB will be rejected by the server. Although not a rule, this is a widely accepted industry standard. You will find most public email servers don’t allow messages larger than 10MB to be sent or received. This restriction is due to server time and resources required to scan and filter large messages and attachments. One common problem with this restriction is sending and receiving pictures. With high resolution digital cameras such as 7-10 mega-pixels it is easy for one picture to be over the 10MB threshold. This problem is easily overcome by using your photo editing program and reducing the size of the picture. You can do this without losing any resolution. Another suggestion is if you are trying to send multiple pictures split them up into separate messages. If you must send out files larger than 10MB we suggest you use FTP site.
