When I send an attachment over 3 mb I get an error message "Could not
deliver
to the recipient" even though the message gets actually delivered.
According
to the customer support from my ISP the problem is with the Outlook
Express
which reports error that the size is over quota (error 5.2.2) even though
it
isn't.
So what *IS* your quota? What is the maximum size for a message that your
e-mail provider allows?
You claim that you are sending a 3MB attachment. Probably not. More likely
is that you are sending a 4.5MB attachment. All e-mail is transmitted as
plain text. Encoding is used for attachment but the section for the
attachment in the e-mail is still plain text. Encoding incurs overhead in
that the size of the attachment will mushroom so it occupies 30% to 50% more
bytes than the original file. You are not attaching files. You are
encoding a section within the plain-text content of your e-mail which
carries the content of the attached file, and encoding will bloat the number
of plain-text characters used to encode that content.
Also, is your quota dependent or independent? You might be allowed to send
10MB e-mails (and that is AFTER any encoding of attachments because *that*
is what the mail server gets) but maybe they restrict your daily bandwidth
quota, your daily message count, the outbound messages share the disk quota
for inbound messages and you have to much garbage clutting up your mailbox
(i.e., you have consumed your disk quota).
No e-mail client reports the message that you noted. That is a status
returned back from the mail server. Call your e-mail provider and get
someone else to talk to. The last person didn't have a clue as to how their
SMTP server works. You could turn on the troubleshooting logging in Outlook
to see just when their mail server spews back that status.
