Limit on email file attachment size?

Limit on email file attachment size?

Is there a 10MB limit on the size of email attachements I can receive with my Comcast email account?

If an email is sent with an attachment greater than 10MB I don't receive it via my comcast email.  I receive nothing, not even the email without the attachment.   A 10MB limit seems awfully small tese days....is it just me of is this Comcasts policy?

I see a message sent from keysight.com (not sure if this is you) on Friday.  It was tagged as a virus, and discarded.  The size was well under acceptable limits.

The maximum size for sending is 25MB.  However, the sender may also have sending limits within their system that limits outgoing attachement sizes, so that would factor into your receiving it.  Where I work, there is  10MB limit in Exchange for outgoing and that roughly equates to about an 8MB file attach.  Maybe contact/research the sender and inquire as to that person's system limitation for sending.

Re: Limit on email file attachment size?

The rough attachment total size is 25MB for all attachments.  This has to do with how the attachments are encoded when attached to the messages.

Re: Limit on email file attachment size?

Thanks for the replies but the problem is not on the sending side because I can receive the same email with a different mail service.  My Comcast email account never sees anything. I would think it should at least send the email with the attachements stipped and give a notification that that is what happened. 

 

I'm sending a zipped directory that is about 6MB after being zipped.  Even after being encoded before being sent out with the email I can't imagine it ends up being over the 25MB limit.  Is there a standard method I can use to test this limt?    

 

Are the files till uuendoded before being sent like in the old days. If so I can try uuending my attachement and see if I'm nearing the 25MB limit but it sure seems unlikely to me.  Any suggestions?

Re: Limit on email file attachment size?

Roughly 25MB should be the limit of the files you're attaching.  Then, yes, they're encoded when attached.  That's why we say it's around 25MB for the limit.  Are you saying you're trying to send the messages into Comcast, or out from your account?  Are you getting an error, or messages are just disappearing?

Thanks for the reply.  I'm sending the email from a non-comcast account to my comcast account. There is no bounced message back to the sending account and nothing shows up in the comcast account either.  It just disappears.

Yep, that's it.  Why would it be tagged as a virus?

Re: Limit on email file attachment size?

Unfortunately, we don't log the type of virus (I'll put in a feature request to get that fixed).  It just says that something in the message was a virus.
