This is one of the anti-spam features of sendmail.
See sendmail.org for details.

Possible solutions:

Ensure that "yaqui.we-web.com" can be looked up in DNS.
Good DNS is always a Good Thing(TM).

Configure sendmail to masquerade "yaqui.we-web.com"
behind "we-web.com".

Add "yaqui.we-web.com" to /etc/hosts.  Doubt this will work.

Create a special class and appropriate rewrite rule
so that sendmail knows that "yaqui.we-web.com" is
all good.
