Problems with Gmail, Yagoo and Hotmail
 
Hello everyone;

I have a "big" problem. Mails from my server are marked as SPAM by Yahoo and Gmail; Hotmail says it's accepted but never delivered.

I have SPF and DomainKeys working; I had tryed the postmasters of the three providers but nothing. The IP address is clean; and the mails marked are just test mails (eg: Subject: Test number one; plus a few words as body).

Yahoo, the only one who replyed something interesting (Hotmail saied "check the Internet Explorer Options", and Gmail sayed "it's spam but I can't telly why)... sended me an email saying:

"The sender seems to have forged your email address in the "reply-to"
and/or the "from" field of the message they sent out. Please know that
we are currently aware of this type of spam and are investigating it."

I don't know why, this is an example of the mails sended and marked as Spam; and everything seems Fine for my Eye;; anyone can see something more?

Thanks...

Hm, looks ok.

Have you checked if your server got blacklisted? http://www.mxtoolbox.com/blacklists.aspx

If not, I'd contact Google and Yahoo.

andresmontanez 3rd November 2007 23:03

All the IPs of the server are Clean (not blacklisted) and they are all in the SPF.
Gmail says DomainKeys Passed; and SPF Passed.

I tryed to contact all providers; and the only one who replyed was Yahoo; saying the above message (forged from or reply-to)... any idea if this is a Postfix problem with authentication?

Thanks.

Does this happen as well when you send that mail from mail.stonetree.com.uy (the mail shown here seems to have been sent form a different server)?

I had made a few adjustemns, sent a mail to Yahoo, it was delivered to SPAM folder... the headers are the folowing:

The MX record for the domain "stonetree.com.uy" is "mx.excelsior.stonetree.com.uy"; it is in the SPF; everthing is OK.

I have Postfix with Virtual Domains; all domains has the MX to "mx.excelsior.stonetree.com.uy".

All the IP Addresses are clean (not blacklisted).

Any idea why Google and Yahoo mark the mails as Spam? Or why Hotmail doesn't deliver the massage (even if the logs says otherwise).

The messages content is rubish (eg: "This is a testing mail").

Could be somthing wrong configured in the postfix + virtual domains?

Try again. When I did (long time ago) they all did reply and told me they added my domains to an ok** list.
**With Hotmail (MSN) it's called Sender ID program. I forgot the name from Yahoo.

I would guess that this is your problem:

Looks like mail relaying, it's from a home broadband account, and to any of the big boys, thats spam.

Thats a good find! Now why did I not see this.

chuckl 5th November 2007 16:49

Thats why they pay me the big bucks. :)

I wish.

Rgds,

Findings...
 
Yes, i'm connected from a xDSL from my Home.
My Thunderbird connects to the mail server (in USA, with static IP, clean as water and reverse dns).
The mail originates from my home; but the sender is the server... could be that? I tryed with others servers and it arrived ok.

I finded that the problem could be the "Message-ID" header...
""Message-ID: <472A7C23.40509@stonetree.com.uy>""

in the postfix page I found this "http://www.postfix.org/BACKSCATTER_README.html"
where it's explained that the Message-ID shoud be "host.domain";
in my case, should be "...@mx.excelsior.stonetree.com.uy",
how is configured the Message id? Or how can this beheavor be changed.

Thanks a lot :)
