Help with IIS 6.0 SMTP server

[Quaylan]

I have set up the server correctly to best i can tell.

it is Pop3 service with smtp on IIS 6.0 on server 2003 small business ed.

I am useing authentication useing windows built in user groups.

Here is my SMTP Virtual Server properties:

Authentication: all are check (anonymous acess,Basic,integrated Windows Authentication)

If i uncheck Anonymous I no longer can log into the server to send emails,

With it checked i still require a password and username..... dont understand this.

under connection i have checked all except the list below,

and under relay I have check only the list below, then i have checkes Allow all computers which successfully authenticate to relay, regardless of list above.

Then I have all my users added to my security list.

other then that all settings are default to the quick wizard.

The problem i am haveing is :

I can send and recieve email from inside the domain , and i can recive email from out side the domain. I cannot send email to some people out side of the domain. Example

I can send email to runbox.com and yahoo.com hot mail ect.

But not to any other email sites.

I get a error message:

The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'somesite@somewhere.com'. Subject 'can't tell yah', Account: 'mail.mydomain.com', Server: 'mail.mydomain.com', Protocol: SMTP, Server Response: '550 5.7.1 Unable to relay for somesite@somewhere.com', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79

can any body help?

Hello, I am having the same problem. I have read almost every forum on the web today. Tried everything they said, and still the server will not send out an email outside my domain. I always receive:

The server rejected one or more recipient addresses. The server response was: 550 5.7.1 Unable to relay for michel@thebigonion.com

my code is simple:

' Send our message:

dim Mailer

set Mailer = server.createobject("CDO.Message")

Mailer.From = "server@mydomain.com"

Mailer.To = "michal@thebigonion.com"

Mailer.HtmlBody = "My body"

Mailer.Subject = "My Subject"

with Mailer.Configuration

.Fields("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2

.Fields("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "mail.mydomain.com"

.Fields("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25

.Fields.Update

end with

Mailer.Send

set Mailer = Nothing

SOME ONE PLEASE HELP US!!!!

Um... The answer to both will take way to long to type, but... The MS Support Knowledge base has some excellent "How To's" for getting server services working.

Link to articles for these issues

Link to MS Support Knowledge base home page <-Just in case first link doesn't work.

@Quaylan

If your using SBS2k3 half your problem is that MS Exchange is installed and not being used. The SMTP service is tied to Exchange by default and should be left there.

Either way SMTP needs to be "fixed" but while Exchange does have a bit of a learning curve...it's well worth it.

For TheBigOnion

Make sure the SMTP Service allows relay.

Go into the Properties of the IIS SMTP Service, go to the Access Tab, then open the Relay properties. Add 127.0.0.1 as allowed as well as the local IPs. This should allow you to send mail through your script.

For Quaylan

The 2003 mail services suck. Try MailEnable. It's free and easy to manage.

If u have AnitVirus Like mcafee Then it is blocking Email Port Because By default it Only allow outlook to send Email other apps can't send.

Note This Property is shown on mcafee Shecdular not on mcshield.

I don't Know about Other AV

Also Check Firewall Setings
