Question : Conventions about sending email

Hi all,

I'm having a argument with a company who is claiming that there are new conventions concerning sending email using SMTP.
Our email relayserver can't be reached using a reverse lookup and we don't want that, but some companys only accept mail when the reverse lookup is enabled.

What's your opinion? Where can I find the conventions about sending email over the internet?

Regards,

Bob

Answer : Conventions about sending email

Digging up the network configuration of your environment is easily done. Using Linux, you can retrieve the outside DNS information using the domain name with one command. So if you give your mail address, please... ;)

I participated in a question quite recently, about an external service that receives mail, does some de-spamming and de-virusing, and then sends it on to the real mail-server through a secure connection. I'll be a bean if I can remember what the service was (poor Dutchism). I'll try to find it, if you think it's interesting.

To get more response, I think you should place additional 20 point questions in other TA's that discuss mail, like Networking. Put a link in that question to this question.
