Re: Email sending problem

[Brad Stone <bvstone@xxxxxxxxx>]

When you specify MAILRTR(*NONE) your email is going like this:


Your IBM i -----> recipient's mail server.

For years now, most people use a mail host.. in house exchange server,
Office 365, GMail, etc.. that means your email goes:

Your IBM i ---> Gmail Server ----> recipient

In the prior situation it may "work" for some recipients, but more and more
are requiring a reverse DNS lookup... that fails and your email fails and
you probably didn't even know it.

The latter situation requires SSL/TLS and authentication.  Lately a lot of
hosts are announcing the end of user/password AUTH and going to "more
secure" things like OAuth 2.0.  IBM i won't do that, and

our MAILTOOL software has had this ability, as well as the basic Auth, for
many years and less than a coffee a day.

Here's an article with most of the methods available:

Sorry, ahead of time, Rob.  I still love you, man.  :)
