simple Postfix question

[timaaarrreee]

hi all,

My SMTP is not working to email other addressed apart from local ones.

So how do i tell the server to use "smtp.ihug.co.nz" to send email?

This is because the webmail feature is not sending to email that are not my own domain.

i.e timsullivan@khost.co.nz TO admin@khost.co.nz works

timsullivan@khost.co.nz TO timsullivan@ihug.co.nz DOES NOT work :(

Are there any errors in your mail log?

it says:

What's in /etc/resolv.conf?

[timaaarrreee]

all it says is : GNU nano 2.0.7 File: /etc/resolv.conf

nameserver 10.1.1.1




10.1.1.1 is my routers IP

Can you try
nameserver 145.253.2.75
instead?

Ok i have changes it but it still isnt sending mail to the outside of my server in Telaen Webmail.

There may be a possibility that my ISP blocks port 25.

And they have tild me that they do not allow mail relaying due to SPAM.

But they did say i could use their smtp server.

Is there a way i can change my config files to use an external smtp server?

[timaaarrreee]

ok i just tried to send to my gmail account and it worked!

But when i send to my isp email i get the nasty messgae. I almost looks perosnel

In webmin the mail que status message:

host zuul.ihug.co.nz[203.109.135.49] refused to talk to me: 554-mx.mailfilter1.ihug.co.nz 554 BLOCKED: The SenderBase reputation of your ISP or corporate mail server is extremely bad.

It looks like my isp has blocked my domain :eek:

I'd talk to your ISP and ask why this happens.
Make sure you have proper SPF and reverse records.

[timaaarrreee]

ok how would i get SPF records to work to that ISP's will accept my mail that I am sending?

[falko]

You can use the SPF wizard ( http://old.openspf.org/ ) and then copy the SPF line to your zone file.
