Question : 530 authentication required

Hi -

I've searched around for a solution to my problem for a very long time now.  I found a lot written about it and I've tried many of the suggestions but still no luck.  Any help would be welcome.  Thanks in advance!

I've included the following below:

CentOS 5
Sendmail 8.13.8
=== bounced mail ===
=== maillog ===
=== hosts ===
=== access ===
=== authinfo ===
=== sendmail.mc ===

The "bounced mail" file shows the authentication problem, although
there's also a troubling "DSN: Service unavailable" message that
appears in "maillog".  I'm not sure whether the two are related or if
the latter is really a problem at all.

Cheers,
Howard

Answer : 530 authentication required

Fixed thanks to Tilman's post on comp.mail.sendmail.

I had smtp.broadband.rogers.com in authinfo, the same as what I had for SMART_HOST in sendmail.mc but I had to change authinfo to smtp-rog.mail.yahoo.com
.
I wasn't worried about this at first because a "dig" on smtp.broadband.rogers.com shows that it resolves to smtp-rog.mail.yahoo.com (Rogers uses Yahoo's infrastructure) so as far as I was concerned it was the same thing.  In fact sendmail ends up trying to deliver the mail to the right place, but beacuse smtp-rog.mail.yahoo.com cannot be found in authinfo, the credentials cannot be found.

Hope this helps someone else!
