Error 550 5.7.1. Relaying denied. Proper authentication require

Hi,

We are using Centos 4.6 with Sendmail (version 8.13.1, config V10/Berkeley). recently we added a new domain "zoharashalev.com" and the customers reported that emails that he send via outlook are rejected,  we tested it with a yhaoo mail box and here is the log:

Mar 10 09:57:47 fastweb2 sendmail[22855]: m2A7vinN022855: from=<info@zoharashalev.com>, size=0, class=0, nrcpts=0, proto=ESMTP, daemon=Daemon0, relay=89-139-198-228.bb.netvision.net.il [89.139.198.228]

Mar 10 09:57:44 fastweb2 sendmail[22855]: m2A7vinN022855: ruleset=check_rcpt, arg1=<idan_hadli@yahoo.com>, relay=89-139-198-228.bb.netvision.net.il [89.139.198.228], reject=550 5.7.1 <idan_hadli@yahoo.com>... Relaying denied. Proper authentication required.

Please help with this.

Thanks,
Amir

Hi,

Sorry for the delay, the customer is aboard and I can't check with her (we suspect that she didn't mark the outgoing server needs authentication). Next week I'll re check it and update the post.

Thanks for the quick replay,
Amir
Thanks,
the user says that now he can send and receive emails but some mail is "lost" in the way (this is another issue that we trying to solve, see: https://www.experts-exchange.com/questions/23256955/Sendmail-problems-dsn-4-0-0-stat-Deferred.html).

So i'm closing this question.

Thanks again,
Amir
