Hello Todd,
Thanks for the reply. I have also got another suggestion from Mr.Odhiambo.
I just applied it and it seems working now. I am monitoring to make sure not
one are abusing our SMTP
Her's the suggestion from Mr.Odhiambo
Look for this in your Exim configuration file:
> # Accept if the message arrived over an authenticated connection, from
> # any host. Again, these messages are usually from MUAs, so recipient
> # verification is omitted.
> accept authenticated = *
> Change it to read:
> accept authenticated = a.b.c.d
> You get it?
> --
