Messages with attachments getting returned

Lately, I have had people tell me that they are receiving a mail delivery error message when trying to send me attachments. Most recently, I had someone send me just 3 small pictures in one message. The error message the sender got was "Diagnostic code: smtp;552 5.2.3 message size exceeds fixed maximum message size." One picture was 6683Kb; a second picture was 5770Kb; and the third message was 7126Kb.

 

This is not the first time that I have experienced issues with receiving attachments. The sender is having to send multiple messages in order to get all the attachment sent.

When the pictures are in the same email, they add up to a larger size than what is accepted by Xfinity mail.

 

If I did the math correctly, adding up the total of all 3 pictures equals 19,579 kb.

 

When converted to MB, the total size of just the pictures in the attachment is 19.120 MB.

 

The total size of your email message, including all headers, text, formatting, and file attachments, cannot exceed 15 MB. As a rule of thumb, in order to allow enough space for the message headers and body, the actual total of all of your attachments should not exceed 10MB.

 

This applies to mail you send and mail you receive. The message is to large for the server, so it's bounced back to the sender.

 

Is everyone who tells you they get the mail bounced back attempting to send pictures? If not, it would help if you could have a couple of them send you the bounce message so you can post it here. Please mention WHAT they are trying to send you.

Re: Messages with attachments getting returned

Recently I have been getting the same error message and, as you say, the photo(s) attachment is at or above 15 MB. But now 5 years later, and with the newer, higher resolution cameras, isn't 15MB a little too limiting?  I would think that the 2012 limit should be raised to 20 MB or 25 MB.
