SPF and SRS

[bangsters]

With a standard installation of scalix on a centos box, how do you add SPF and SRS? I just noticed that email being sent uing my scalix webmail is not being received by hotmail....

any suggestions?

EDIT:

What do I need to be able to send to hotmail, AOL, etc? I aready have PTRs set but I still cannot sen to these emails...

I am looking for the same solution myself- and not with just SCALIX either. Im seeing posts all over the web related to the same issue.

Here is the link to the problem for everones reading if the want it. http://grownupgeek.blogspot.com/2006/12/getting-email-around-aol-and-hotmail.html

I have had the same issues these guys have had for 3 weeks since implimenting SCALIX and another 2 test servers I am testing with under CentOS and RHEL4 with ISPCONFIG and the simple Sendmail. I am guessing the answer is to add the SPF record under the Linux OS you are operating under in the DNS CFG- but where- Im clueless as well. =)
Ill keep searching and If I find it, I will re post back here with what/where and how.
Cheers.

This has to be done on the DNS servers for your domain. If you don't manage them you have to request your DNS admin to do it for you. If using NAT you need to add records for the public IPs.

If your using linux for DNS, at tht bottom of the previous link, it explains what to do in linux to your zone file(s) -look directly under the windows DNS server walkthru where it mentions BIND. However, if you need more assistance, try: https://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/ref-guide/s1-bind-zone.html -this is for redhat- but other linux engines are very similar.

For your SPF Questions and your external DNS/ Registar needs:
If you need help creating the spf record, then go here and create one.
http://www.openspf.org/
Then you will need to copy the spf data and insert into the DNS/ Registar records as a TXT record- most likely in the same place where you have created your mx, ptr, a or c records to point your domain name to your public Nat'ed IP destination.

Now- for common sense sake-just in case someone reads this and says- 'cool Ill just slap my Ip in there and it will work!'...Remember: Dont point any record to your Private IP behind your firewall/ or on your internal network that server is physicaly on- it wont work. It needs to be the Public NAT address your web site is at ( i.e. if you Ping pinkdinos.com and it returns an IP of 65.321.45.176 - the 65.321.45.176 is the Public IP you need to point to).

Your Registar should have an option for TXT record, if you cant find it- call them and ask them where it is or if they can put it in for you.
