I am trying to send email to clients and I am getting an undeliverable 554
service unavailable message. What does this mean and how can I fix it?

Regarding error messages:
- Do NOT describe an error message.
- Do NOT summarize an error message.
- Do NOT paraphrase an error message.
- Do NOT truncate an error message.
- Do show the ENTIRE message (but munge/star out personal info,
like your username).

The EXACT text of the message should help. The 554 error usually means you're
not authenticating properly to the outgoing server, but without the exact text
of the error, that's not a definitive answer.
