Message size exceeds maximum

Postby jimlaur » Thu Jan 23, 2014 12:14 am

Hi,

I suppose that the diagnostic message, below, may be misleading or that I misunderstand it.
Also, I have not been able to find any discussions in this list about this problem.
Still it seems right to ask here if you see anything that might help, so...

I recently had one person fail to send mail to me with an attachment.
They tried several times.
This is the only time I have seen such a problem, which is odd.
I believe the rejected mail message was at most a couple of MB.
I know I have received larger messages in the past.
The sender sent this stuff to a bunch of people and only had a problem with me.

The message below is what was bounced back to them:
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Your message cannot be delivered to the following recipients:

Recipient address: xxxxxxxxxxx@dfgh.net
Reason: Server rejected MAIL FROM address.
Diagnostic code: smtp;552 Message size exceeds maximum permitted

Remote system: dns;gourmet7.spamgourmet.com (TCP|167.206.4.196|62400|216.75.62.102|25) (spamgourmet. helo.)
-----------------------------------------------------------------------------------------

So, it appears to me that spamgourmet may have rejected their mail.
Is there a maximum message size policy at spamgourmet?
If there is, what is it?
Do you know what is wrong or have any suggestions of how to proceed to understand the problem?

Thanks for your help.

My friend, you devoted so much time to writing this when all it took was a few seconds of searching:

Thank you lwc, I appreciate your help.
It is not that I did not search, it was that I was not clever enough to choose the right search terms.

To summarize what I read in those links:
SG does not impose a limit but there is a limit enforced by the mail system in the server.
Early on this seems to have been 5MB, but it may be larger by an unknown amount now.
Large attachments do increase the work SG must do, and that will not change, so having some limit is a benefit to SG.

It seems to me that attachment size limits might be a suitable topic to include in the FAQ.

I agree that large email attachments are to be avoided, I fight that fight, but there they are.
There ought to be a better way, but we are not going to change all those email clients.

In this case I was not expecting an attachment at all.
The sender was upset because they could not send me mail, so I offered to find out what happened.

Thanks again.
