SMTP Proxy envio de email ficam na blacklist DUL

Ora cá estou eu outra vez, antes de usar o endian os meus emails não ficavam bloqueados em lado nenhum e agora estão a ficar bloqueados nesta blacklist: MAPS DUL da micro trend (http://www.mail-abuse.com/cgi-bin/lookup)

Já fiz uma carrada de alterações e não percebo o porque.

O endian é quem faz o envio dos emails e o meu ip é estático.

Segue em baixo o mail deles para resolver a situação:

TEP 1: CHECK YOUR EMAIL CONFIGURATION

Here are two things to check about your mail configuration:

Email Client

============

Check that the Outgoing Mail Server (SMTP) setting on your

email client (such as Outlook Express or Mail) is using

the outgoing mail server for your ISP. Most ISPs require

that you use their mail server to avoid spamming incidents.

Email Server or Proxy Server

============================

If you run a mail server on your computer, or if your local

network uses a proxy server, set the SMTP Gateway setting

on the mail server or proxy server to your ISP’s outgoing

mail server. This will force your mail server or proxy

server to send all outgoing mail to the ISP first, and then

the ISP will relay it to its final destination.

====

Note: If you are a RoadRunner business customer, you may

need to contact your ISP to get your business IP marked as

static. They will then let Trend know of the change.

STEP 2: CONTACT YOUR ISP

If the two steps above do not solve the blocking issue,

then If the two steps above do not solve the blocking issue,

then the rDNS for the IP may need to be corrected to

clearly indicate it is a static IP.

Trend’s Spam Investigations team can work with your ISP

to solve the problem. You can find the correct email

address to use when contacting your ISP to use by going

to the following web page and typing in your IP address:

http://ip-lookup.net/

Then click on the Domain owner info (Whois /Abuse) link

and look for an email address. You can use this address

to contact your ISP and ask them to work with Trend Micro.

The ISP can start this process by sending an email from

their Domain owner email address to dul@mail-abuse.com.

Thank you for contacting Trend Micro and we hope this email

has helped you to resolve the IP blocking issue.
