I can't send an e-mail

[maruja]

I'm trying to send an e-mail and it returns to undelivered mail to sender
with this message: The mail system

<[email protected]>: host 157.100.1.2[157.100.1.2] said: 554 5.7.1
<[email protected]>: Sender address rejected: Access denied (in
reply to RCPT TO command)

What this means and what I can do?

I checked that Comcast email address, and it is valid.
It appears that you are sending via a mail server in Ecuador.
Try this:
Make sure you have send authentication enabled.
Go to Tools, Accounts, select that account, Properties, Servers.
Enable the "My server requires authentication" option.

If no improvement, give us the outgoing server name, port number,
and any special settings you have for that server.
