I am using Apex to send emails with attachments to users.
For incoming emails, I know the maximum size of the email, including the attachment, is 10 MB. Email which are above 10 MB are not processed by Email Services and are rejected with an email response back to the sender.
However, I am having trouble determining the maximum size for outgoing emails. I've heard there's a 3 MB limit but haven't seen this documented.
Can you all confirm an outgoing limit on email or attachment size?
What happens when the limit is exceeded? What kinds of errors would I see?
Is there any way to send emails more than this limit without leveraging any appExchange tool? Any ways?
Thanks in advance.
