Maximum e-mail attachment size question

Why is Comcast's maximum e-mail attachment size only 10MB?  This seems small to me and it's often not enough for me.  Especially since some files expand in size when you attach them.  In those cases, it'll only upload if the original file is only around 8MB or less.  It seems most servers have a maximum size of up to 25MB.  Why can't Comcast have that as well?

Re: Maximum e-mail attachment size question

Comcast's limit is actually 15MB, but to allow room for headers, etc. the actual limit is closer to 10-12MB. 

 

As for why some email systems now allow larger attachemnt sizes: while convenient it's not necessarily a good thing. Email systems were never designed to move such large files, and when you add that to the amount of spam that is generated on a daily basis, it's a miracle that our email systems don't shut down more often than they do. 

 

In the old days, it was FTP that was designed to move large files across the net. Today, cloud-based storage systems like iCloud, Dropbox, even your Comcast online storage make this easier and faster.

That's a good explanation and yet somehow it still says that Comcast's email is just inferior to may others who allow you to send a number of decent sized pictures all in the same email. Smiley Sad Soo sad for Comcast.

Are you using the xfinity webmail client, or some other client like Thunderbird?  We normally allow 35MB - if you're seeing different, then (once you confirm), I'll alert the webmail folks.

 

Thanks,

When did this change from 25 MB?  If it is indeed 35 MB now, this page needs to be updated.

Re: Maximum e-mail attachment size question

I was trying to send 6 pics from my iPhone.  The total size was actually less than 1MB.  I sent the same email with a buisness class gmail account without incident.

That's 35MB after encoding for transport.  So roughly 25MB of attachments, from a user's perspective.
