[calvin]

I have somre problem with send e-mails for some domains, I am receiving this message:

<user@doman.com.br>:
Connected to 200.174.111.5 but sender was rejected.
Remote host said: 501 5.7.1 <admin@xxx.br>... Sender IP must resolve

I contact the ISP and tell that is blockig e-mails that doesnt have reverse.

calvin,

This is not an SME problem. It is a DNS issue that you need to work out with your ISP / DNS Service provider.
