My Emails For Both Support ( at.zaxihosting.com) and sales goes to junk folder of the most mails companies(yahoo,hotmail)
Reserve For the mail ip is " ZaxiHosting"
How Can I Fix This?

You mean reverse DNS?

In general if you have a reverse dns entry for the ip that you are using to send emails, there should not be any problem.

Yes Reverse.
Hm Dont Know.
Many customers says that goes to spam folder and others that the mails delay.
The problem is more with yahoo.
Regards

Is your server an open relay? This is another way that could "blacklist" you.

On the other hand this behavior could be normal if you are using some kind of promotional language in your emails.

Main text is orders confirmations,invoice,etc
Don't know why.
I have changed the mail server ip around 5 times(6 are all the ips I have) but again nothing(maybe because they are physically hosting in the same machine)

This problem is common with old "used" IP addresses and mostly web based mail systems.

I think you must be very careful with your servers IP address that you didn't get listed as spammer by the gmail community

Hm...
And now what Can I do?The main problem is with yahoo mails.
Regards

don't know about yahoo, but let us do a test, I send you some mail from a web server where I know that mails going to the spambox and one from a server with a new IP address where I believe that mail comes in the same inbox.

If you like, send me some test email addresses to olaf at webdigity dot com

Hm..
I change the email in the WHMCS from sales to info and in yahoo now the mails goes to inbox and not to spam folder.
Will see
Regards

It looks like yahoo has a "great" antispam system.....

Awful..
I have about 10-20 emails from yahoo.
It's Important to me.
I send an email to yahoo too.
Maybe solved.
Regards
