SMTP Problem: Mail stuck in queue.
|
|
| James Goodman 2004-11-26, 5:50 pm |
| I have a Win2K domain controller, running IIS with SMTP.
This is connected through a router to the internet.
I need it to be able to send emails from asp pages.
I have tried all the configuration options I can think of, but messages
always fail.
Do I need to configure a smart-host? Why?
The server in question has been rebuilt. I checked out the SMTP settings
before rebuilding it & the only things I could find specified were a smart
host. I have configured this as it was, but the mail just sits in the queue.
Any suggestions?

No. Because you don't.

Normally this is a DNS issue. Check DNS settings on the server. Also
check the SMTP logs, evebt logs and NDR's if you have any. A second
possibility is you're not routing them or you have a firwall blocking
them.

| Hello,
In general, there is no requirement for a smart-host, but in your case, it
might be a requirement. For example if your ISP blocks outgoing port 25, for
all machines except the ISP's email server, then you need to use your ISP's
email server as a smart host, because that will be the only server able to
communicate with other servers on the Internet.
I would recommend you to look in the event log (Start->Run, eventvwr.msc),
it can usually tell you why the emails are not being sent. Usually, it is
because blocked port (your SMTP server will not be able to communicate with
others), or DNS issues (your SMTP server cannot find other SMTP servers).
If you do not understand what is written in the event log, please report
back here with the complete message, and we will try to help you. You might
also have some use for www.eventid.net, which has many good suggestions for
solutions to different messages in the event log.
Good Luck!

| Thanks for the responses. It turns out to be much simpler:
There was no problem with my SMTP server. The email provider we use for our
company will not allow us to send email from our SMTP server, stating we
need to use a smart host. I enter the smart host as specified but it still
rejects. I am therefore guessing it is a problem their end, not ours!
