Hi,

I just got enough of exim so I decided to move to exim4. I think that I configured it properly (similar way as the exim3) but when I'm sending mails to my yahoo account then I got a spam warning and my mails are moved into the Bulk folder.

I didn't give any hosts or domains additionally to relay for (aonly the default localdomain is set automatically by debconf). Do you know which are the crytical lines in the exim4.conf.template file what I have to take care on?

Thanks!

This would be a problem with your yahoo account, not exim. Just set up your yahoo account to stop treating mails from your server as spam.

Why are you mailing yourself anyway?

Thanks bulliver!

I just sent the mail in order to check whether my exim4 server is running properly or not. Earlier I had some problem configuring exim3 because it was treated as open relay for a while. I fixed it and it was not an open relay anymore (it was 2 years ago). But now I had problem with exim3 cause it doesn't let me send mails. Something always keep changing the ownership of the "mainlog" file in the /var/log/exim/. I made a try to see if exim4 is doing the same stuff but I also wanted to check if it is configured well.

Thanks anyway!

Yahoo might be listing you as spam if you do not have a proper PTR record for your IP address. I know AOL/TW do that sometimes too.

Thanks charon79m!

Could you please tell me a bit more about PTR recor of the IP address and how it can be configured?


Thanks!

PTRs are configured by the ISP... unfortunately you have no control over them.

If a mailserver is configured to check PTRs when an incoming email is received the server takes the source IP address and does a PTR lookup. It then makes sure that there is a valid PTR entry for the IP, it not it will reject the email. The theory is that if the mailserver is valid, then the company that owns the server would contact their ISP to have a PTR setup.

You can check what your PTR record is for your public IP by doing the following (Windows or Linux commands are the same):

nslookup (runs a command called nslookup)
set type=ptr (lets nslookup know you want to know info on PTR records)
x.x.x.x (Your public IP address, you can find this by going to http://whatismyip.com)

Below is the results off one of yahoo's IPs:

184.75.218.66.in-addr.arpa name = l1.login.vip.scd.yahoo.com

Now, some may say that nslookup is an antiquated application and that we should be using "dig" for this... perhaps they are right... I'd learn to use both you you are interested in computer networking.
