Hi

When I try to send jpg images which are 5MB in size from Outlook
Express, I get an error message like that below

"The following message to was
undeliverable. The reason for the problem:
5.1.0 - Unknown address error 552-'MAIL
max. message size exceeded"

When I contacted my ISP, they advised that the max. size of mail
from OE is 5MB.
Is this a restriction within OE or is it a restriction applied by my
ISP??
If these restrictions cannot be removed, is there any way around
this issue so that I can send large image files?

Thanks

OE does not have any size limitations. Your ISP and your friend's
ISP likely do though. I'm going to guess that the message means
your friend's ISP is the problem one because usually if it's your
own ISP the message is less cryptic OR there isn't even a message,
just a failure.

The only way around it would be to break the message into two parts
so they are each smaller. 5 MB isn't actually the size of message
you can send, either. E-mail must add "overhead" data to your
e-mail, so the actual max you can send might be closer to 4.5 Meg.

Such information -should- be included on the ISP's sites under tech
support areas.

You added overhead and the size is smaller?

Attachments must be encoded as text which adds 33 1/3 % to the size
of the email.
So a 5 MB attachment will be 6.7 MB email.

Yes; I stated it correctly. The OP cannot Send if it's close to 5 Meg; it
has to be SMALLER than that. With overhead added, the message the OP can
Send successfully is going to be LESS THAN 5 Meg. The size (5 Meg) the ISPs
give typically does NOT include the overhead since it's hard to predict what
the overhead will be. BTW, your rule of thumb is a decent one.
So the sender usually ends up guessing at how close to the stated limits
his mails can actually be. If the OP sent a 5 Meg attachment, it would fail
because it's over 5 Meg; he has to make it smaller. Or break it into
smaller pieces and multiple e-mails if the REceiver knows how to reassemble
them. In my case I have a 10 Meg limit and normally can't send anything
abt 6.5, sometimes closer to 7 Meg. For mine it's not just the attachments;
it's the e-mail total size. That's likely the OP's situation also.
