Here are some suggestions that may help you with those "UNDELIVERABLE" error messages and "REPLY" issues (concerning Craigslist Ads).
Make Sure the Ad Has Not Expired:
Go DIRECTLY to the original ad and make sure the:
Ad is NOT expired;
Email address in the "Reply" button is the same.
Always read any ad very carefully and check posted date.
Sometimes, the "REPLY" email address changes. Double-check the actually email address in the original CL ad.
Your ISP or File Attachments were TOO BIG:
Sometimes, it can be your ISP [ Check out " Fixing DNS error messages "] or your IP address is simply blocked by Craigslist. Try using a VPN. (If you're an approved member of RemoteWriterJobs, check out out Member's Forum for more resources and tips.)
.....Other times, it can be large file attachments that cause the email relay for CL to behave badly.
Attach smaller files to your email.
If your file attachments are small (and that's not the problem), then try this:
