When I reply to craigslist posts, my message is rejected. It was working up until a couple of months ago.

SMTP error 554 is one of the more vague error codes, but is typically caused by the receiving server seeing something in the From or To headers that it doesn't like. This can be caused by a spam trap identifying your machine as a relay, or as a machine not trusted to send mail from your domain. This may also be due to reverse DNS lookup not being properly set up.

You should talk to your email provider and/or hosting provider.
