Unable to send to this email address in Yahoo! mail

Question

I'm on the non classic interface (the standard gui) I tried to send an email to

users-digest-subscribe@httpd.apache.org.

The email address is valid and I'm able to send to it via another client or the older interface, but with the standard gui, I get the message

Invalid Address:

We cannot find a match for this email address:

users-digest-subscribe@httpd.apache.org.

Please use an email address that looks like user@example.com or a nickname or a distribution list name from your Yahoo! contacts.

Does anybody know how I can send the email to that email address with the standard Yahoo! mail GUI, and without getting that error message?

Answer 1

You have a period at the end of the email address

users-digest-subscribe@httpd.apache.org.
                                       ^

It should be users-digest-subscribe@httpd.apache.org (no period)

Removing the period gets me a reply from the Apache Digest with the subject

confirm subscribe to users@httpd.apache.org
