 For all message size limits, consider that Base64 encoding increases the size of the message. You need to increase the size value to account for the message size increase that occurs after the message attachments and any other binary data are Base64 encoded. Base64 encoding increases the size of the message by about 33%, so the message size is about 33% larger than the message sizes before encoding. For example, if you specify a maximum message size value of approximately 10 MB, you can expect a realistic maximum message size value of approximately 7.5 MB.
