Default Have many questions but will start whit 1 (mailing)

Okee here we go again,

I have been able to set up my first Linux server using the perfect setup tutorial.
I have an site up and running http://www.gratizenvoornix.nl but want to give the user also an email like info@grat.....nl.
Im reading the forums over and over but cant find any good explanation for my problem.

I know my port 25 is blocked, therefore I have an acount at rollernet to relay my email. I think I have to put some configuration somewhere in postfix.

I know this is probability a very basic thing to do but I cant find out how. There's so many info on the forums that I am starting to get very confused

Hope someone has the time to help this Linux noob.

TIA

In Holland, al lot of Internet Service Providers are blocking port 25.
Reason: to avoid spam
If so, you only can send e-mail with the smtp server of your ISP.
It has nothing to do with your Postfix configuration.

There are some ISP's who do not block your port 25, like XS4ALL and Quicknet.
You can consider to make a switch ...

Hans,

I know that my isp @home is blocking the 25 port. But I have red that if I want to use my own server i have to use smpt relaying. From oa Rollernet, Dyndns or something like that.

Quote:
@Home heeft poort 25/tcp voor inkomend verkeerd geblokkeerd. Mailservers luisteren normaal op poort 25/tcp naar inkomend verkeer, zodat ze emails kunnen ontvangen. Door de filtering van poort 25/tcp wordt het direct ontvangen van mail op je eigen mailserver technisch onmogelijk omdat elke mailserver ter wereld er vanuit gaat dat je mailserver op poort 25 luistert.

Via een omweg kan het wel. Je kunt je email laten bezorgen bij een andere mailserver buiten @Home door het MX-record in de DNS records voor je domein naar die mailserver te laten verwijzen. Die mailserver kan vervolgens de mail voor jouw domein doorsluizen naar je eigen mailserver op een niet-standaard poort (bijvoorbeeld 2525). Dit kan echter alleen als de beheerder van die mailserver dit speciaal voor jou heeft ingesteld.

Er zijn een aantal bedrijven die deze service gratis of tegen betaling aanbieden:

* Rollernet.us (gratis)
* DynDNS.org MailHop Relay
* No-IP.com Mail Reflector
If I understand you corectley I must be able to send and recieve mail instantley?

I do not recommend to send e-mail via smtp over another portnumber then port 25.
Of course you can point the MX10 record within the DNS records of your domain to the Rollernet mailserver and configure your MTA to use another port, it's up to you.
You also can make use of the smtp server of @Home within your e-mailclient or as i've said before make a switch to another ISP, who do not block ports.
