Hello

For a number of weeks I have been struggling to get my SMTP working. 

I am using asp.net 1.1 and DNN 3.2.2 with SQL Server 2000

I have scoured the DNN search and Google but I have not yet found a solution. 

My hosting provider insists that they have allocated the correct settings and everything is in working order, that the error is with DNN coding.

I am able to send and receive emails directly and even via using the feedback form on the site.

Yet despite this on every Host SMTP test I keep seeing this error:

Could not access 'CDO.Message' object

The error log file is:

I have since installed CATALook  and tried to send email through the module, I was taken to this error page:

I need help, can anybody please advise what I might do to solve this problem. I am not a programmer and I am unsure what I should edit, in case I make things worse.

Thanks.

Make sure that your Host Setings email and the email address for the Administrator of the portal are valid addresses.

Hello Mitch

Thanks for the reply.

I have just re-checked just to make sure.

Yes all emails are valid, I can send, recieve and view via  logging in on my host control panel.

I forgot me mention, although I can only access emails via the hosting provider ( JodoHost) control panel ( not via host on my site) I can send and recieve via the panel of the hosting provider site, I still am unable to get the SMPT to configure on my own site. 

 It is vital to get the emails working, the site is becoming an expensive white elephant in time and money and is completley useless without it. We have been without SMPT emails from the start and I have spent weeks trying to find the solution. 

Any more suggestions, please.

What are the smtp settings under Host > Advanced Settings > SMTP Settings

Are you using Authentication?

Hi J7Mitch

Thanks for the reply

SMTP Settings:

SMTP Server:    mail.mywebsite.com

SMTP Authentication:    Basic

SMTP Username:   HostProviderUserName@mywebsite.com

SMTP Password:  HostProviderPassword 

 

Thanks

I am getting an almost identical error:
InnerException: Could not access 'CDO.Message' object.
Message: System.Web.HttpException: Could not access 'CDO.Message' object. ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.InteropServices.COMException (0x8004020F): The server rejected one or more recipient addresses. The server response was: 551 Bad Recipient --- End of inner exception stack trace ---

The SMTP server is working fine, as I can send and receive emails from a remote client using Outlook Express/Thunderbird etc. using the same email address as for the SuperUser/HOST login.

The 'Test' function for the mailserver on the Host Settings page works fine: it sends and delivers a message to the email address listed above there on the same page ('Host Email').

However, the Password Reminder button does not send an email. The operation appears to complete, but in the Log Viewer, the message above is recorded (and being ignored by the Password Reminder page).

We recently moved hosting companies, and it was working fine with the previous one.


Any ideas?

Thanks!

Hello mdskelton

My hosting provider insisted the fault was on my website and everything was working perfectly with them.

I searched for several weeks of trying to find a solution, it is not much help to you but nothing helped. I gave my hosting provider  (HOST) permission to see for themselves as they seemed to think that I didn't have a problem. Only then did they appreciate the problem and suggested I used localhost instead of mail.mywebsite.com for the time being.  It worked.

SMTP Server:    localhost

SMTP Authentication:    Basic

SMTP Username:   HostProviderUserName@mywebsite.com

SMTP Password:  HostProviderPassword 

Only yesterday, did my hosting provider admit that the fault was with their server all the time and has only now rectified the fault.

My SMTP is now working as intended using : mail.mywebsite.com instead of localhost.

I have asked them what exactly caused the problem, but I have yet to receive a reply.

Providing all your setting are correct, valid email etc., and because your SMTP worked before, I would suggest that you ask your new hosting provider to re-check the settings on their server.

Sorry I don't have a fix it solution for you. Good luck.

Lynn

Thanks Lynn

It looks like I am in the same situation as you. When this gets resolved, I'll post the fix here.

Those settings should work.

If you want to give me access to your environment, you can contact me through the e-mail on my profile or private message and I'll see if I can figure out why it isn't working.

Hi all

There were several problems.

The main SMTP server on the machine could not be configured to talk to web applciations, and a second SMTP server program was available to do this, on another port (i.e. not port 25).

HOWEVER, it turns out that DNN does not allow you to specify an SMTP server on a port except port 25. In other words, a setting like this will not have the desired effect:
localhost:587
The port is ignored by the System.Web.Mail.SmtpMail class as used by DNN. I checked the source for DNN 3.2.2, and the port number is NOT parsed out from the servername string. This seems to me to be a serious limitation. A line or two of extra code would enable mail sending on alternative ports: parse out the port number, and if its there, set the port explicitly for the mail message before sending.

So I was left having to use a server on the default port 25, but with only a single machine it's tricky to get SmartHost relaying working properly (perhaps impossible).

In the end, I disabled the two existing SMTP servers, and installed MailEnable:
http://www.mailenable.com/standard_edition.asp
This is free and very easy to use and configure. Crucially, it can listen on two different ports, and had no limitation wrt web applications.

I highly recommend it if you are having similar problems.
