Hi, It seems that the mail forwarding service has a size limit of about 20mb, as I am getting incoming mail bounced by mail.zoneedit.com. Is there a stated limit somewhere, I wasn't able to find it. Is it possible to increase the limit using credits? Thank you!
 
there is a 25MB limit including all headers as well.
and sorry, iti s a global setting and cannot be modified.

regards.
 
Thank you very much! It's interesting, I thought the limit was lower. Gmail also has a $25mb limit, yet the same large email was rejected by zoneedit while it was accepted by gmail.
 
hi again... by chance do you have a copy of the returned message headers?

regards.

... while talking to mx-caprica.zoneedit.com.:
>>> MAIL From:<s...@.....edu> SIZE=31363700
<<< 552 5.3.4 Message size exceeds fixed limit
554 5.0.0 Service unavailable

The mystery part is that the same email message went through fine when sent to a gmail account. The attachment size is shown as 22mb (23,213,469 bytes to be precise). Thank you for looking into this!
 
there is additional header data when a message is forwarded compared to sending straight on to an intended recipient.

regards
