I run a classic asp website in which several thousand emails are sent a day through SMTP. I use Cdo.Message. A single "To" Email address and a Single "From" email address are used. The majority of these messages are received; however, recently several messages each day are getting stuck somewhere (not sure where).
Logs show that users have accessed the page; therefore, the message should be sent (It is sent on page load). There are no traces of emails not sent in any of the SMTP folders. Where else should I look?
Could those users be search engine robots? What does it take to get to that page? how about robotic submissions that are brute forcing their way thru?

Email is sent using Amazon simple Email service form my website. When an email is sent to any Yahoo or Gmail address, it is delivered to Inbox; but when it is sent to Hotmail,it is delivered to Junk.
Why only Hotmail Treats my email as junk?
When an external user sends email messages to an Outlook.com account,
SmartScreen® filter technology evaluates the content of the messages
and assigns each message a rating based on the probability that it is
a junk email. This rating is stored as a message property called a
spam confidence level (SCL) within the message itself. The SCL rating
stays with the message as it is sent to other anti-spam protection
layers within Outlook.com. Rules inside Outlook.com are set to handle
email messages with various SCL ratings. If a message has an SCL
rating lower than a certain threshold, it is considered to be spam,
and a rule then deletes the message rather than sending it to the
user's junk email folder. If the message has a higher SCL rating than
the threshold, the email is delivered to the user's junk email folder
rather than to the inbox.

Not all the Anti-Spam system depends only on 3rd party blacklists. Major email service providers builds their own reputation table in addition with the use of major 3rd party blacklists like spamhaus, barracuda etc. In your case, you are using Amazon SES to send mails.
I, myself found enormous marketing mails coming from Amazon SES. If the reputation of your email service provider is bad in hotmail then it may trigger the suspicious level of your mail regardless of your email service provider reputation at other blacklist providers. In addition to this, if your subject, body content contains some suspicious words then your mail will end up in junk folder.
Most emails sent from third party applications such as Wordpress, Joomla, or Amazon get diverted to junk and sometimes they fail and get stuck behind a security layer. I know for a fact with Wordpress Contact Form 7, this is the case many times.
After so many years and finally attending a seminar for this particular issue, I finally was able to solve this problem specifically for Hotmail (Outlook.com).
Before you do anything ensure your SMTP settings in your web config file (ASP.NET) are written correctly or in case of plugins (Wordpress) make sure the fields are filled correctly. This means ensuring these are the settings you are using for Outlook:
From: your email ("asdf#outlook.com")
From Name: "Your name or company name"
Host: smtp.live.com
Type of Encryption: TLS
SMTP Port: 587
SMTP Authentication: Yes
Username: Same you use to login (usually the complete email address)
Password: Enough said there
IMPORTANT - Send a test email even if it fails. The point is to trigger an activity in Outlook and have them flag it as an
unauthorized connection
Now, to the fix:
Go to Outlook.com
Login
go to Account Settings
Choose Security & Privacy
Click on "See my recent activity"
The most recent activity should be the fail attempt. Authorize it as a trusted connection.
Done!
Re-test and you shall see your emails showing in the inbox as an authorized connection. Doing these steps let Outlook know that your emails from Amazon are legitimate connections and not Amazon trying to spam your account with solicitations etc.
Mostly it is a email service provider specific thing but you can do below checks
Ensure valid sender email address
Try not to use keywords like gift, prize etc. which are preferably spam activities

I have site where people can send posts (Wordpress based website). Each post have a form which anyone can use to send email to the author of the post. I think at some point there might be heavy traffic on site and that could mean hundreds and hopefully thousands emails leaving from different posts pages per day. What should i take account that the emails don't get attached to spam filters? Or should I use some 3rd party system for this?
One thing that I usually do by default is add a TEXT record to my DNS (SPF Record) indicating that this server is an authorized sender for my domain.
If the server is on the same network as your mail server, you can relay the mail through your mail server.
If the mail server is not on the same network, you could sent the mail through SMTP.
Make a reputation system of your site users ( like stackoverflow for example) and give mail power just to those that managed to get a number of points ( or whatever you will use for reputation). This way, at least, you won't get abused by spammers. Moreover, if someone abuse his power, you can "ban" him from sending emails.
About spam filters, if you have a dedidated server, could use your local smtp with some antispam solution instaled, to drop those messages that are spammy, to stop them at the source.
Also, use SPF and DKIM but those won't ensure that your mails won;t end up in trash, just protects your identify as mail sender, and others can't impersonate you.
I am developing a software but for that I want to know as if i send an email then how can i check the sent email is in recipient's inbox/ Junk.
I am using AsP.net and c# technology for this
Please reply
You can't detect what is done with the email once it is delivered to the users inbox other than requesting a delivery receipt and a read receipt but the user can opt out of these.
The best way to avoid being marked as spam is to use a trusted third party service such as Campaign Monitor or MailChimp.
Failing that you should make sure that your email has a proper from address set, that you have set up SPF records to allow the sending IP official permission to send email on behalf of the from domain, keep your html to content ratio reasonable and if possible use an email address that your customers have already received an email from before so that there is a higher chance that the address is already in a whitelist.
You really can't because there are many different email spam solutions out there and they don't send a status back saying whether they delivered the email to the recipient or not. What you can do is send an email with a tracker to see if the receiver opened it.

I am building an intranet site and i want to display the users email(not the complete email), but the subject, from, date and time.
However, the first step would be connecting to the exchange server using the NTLM credentials, which are the same, however, i dont want the user to have to type their password to connect to the email.
is this possible and how?
any resources/examples anything to help me get started thanks
I have created some webforms that will allow users to fill in their data. Afterwards, the information is processed and inserted into a database with a follow up email to me afterwards letting me know who signed up.
The problem is that I use different email addresses on all of these webforms.
What I would like is some sort of dashboard email application where I can view all the emails being sent to me from one central point.
I think that Thunderbird allows you to receive multiple emails from different accounts. Is something like this even possible?
You can configure just about any email application to receive mail from multiple accounts. Thunderbird does this as does outlook (not outlook express). Just go through the normal process you do to add an account, then go ahead and add another account under a different email address.
Here's a link to a walk through on how to do this on Thunderbird.
