Any suggestions? We are using PageGate v5.0

If you would, run this test for me:

1) In Windows, run a Command Prompt.

2) In the Command Prompt, type the following and hit enter:

telnet smtp-bb.vtext.com 25

Let me know what the response is, please.

554 njbrspamp1.vtext.com

Connection to host lost.

[Tech Support]

Okay, that's a 554 rejection notice. It means that your public IP is on some form of grey or black list.

The first step in resolving this issue is to find your public IP address. The easiest way to do this is to go to the following website, from the computer that is sending out the SMTP messages:
http://whatismyipaddress.com

Next you will want to find out if your IP address is listed with one of the major blacklists. There are a variety of resources available for this, such as:
http://whatismyipaddress.com/blacklist-check
http://www.mxtoolbox.com/blacklists.aspx
http://www.senderbase.org/home

Once you’ve determined what your public IP address is, go to one of these sites and perform a blacklist check on it. In the results of the lookup, you should see which, if any, blacklists your IP address is listed on.

If you find that your IP address is listed, you have a few options:
1) Attempt to delist your specific IP address from the blacklists by notifying them of the problem.

2) Contact your Internet Service Provider and inform them of the MTA downgrade and resultant blacklisting. Hopefully, your ISP will work with you to resolve their IP range’s status as untrustworthy.

3) Change your method of delivery to relay through an SMTP server.

Each blacklist has a website associated with them and most have a procedure for delisting specific IP addresses, because false positives can happen. Earlier, we mentioned that your IP being listed as a result of your ISP’s IP range being untrustworthy, is only one possibility for your IP being listed with the blacklists; When you perform the blacklist lookup on your IP address, pay attention to the results. Sometimes, if a system or server on your network is infected with a particular type or style of malware, your specific IP will be blacklisted. The lookup pages will provide the information relevant to why your IP was listed.

Once you’ve determined that your IP address is listed, you can submit a delisting request with the blacklist hosts. These requests generally take a minimum of one business day to process and once the request has been approved, your IP will be removed from the blacklist. However, this may not be the end of the process. If your IP was listed because you have a malware infected system on your network and you don’t identify and remove the malware, your IP will immediately be listed again. Similarly, if your ISP’s IP range is listed, rather than just your specific IP being listed, your IP will immediately be listed again.

Could the blacklisting be due to a higher volume of pages? If I switch to relaying through an SMTP server, is there a chance that address would be blacklisted?

[Tech Support]

Honestly, if you're not sending out a tremendous number of messages, your impact on the MTA record and the IP's subsequent blacklisting would be a little negligible. It's really unlikely that your particular network or system was the cause of the blacklisting.

If you switch to a relay, there's really no chance of it being blacklisted. Proper SMTP servers are configured to actually be registered as sources of traffic. the only way you could get your SMTP server blacklisted is if you were using it, literally, as a spam gateway.

Can I move the messaging over to our exchange server and use that as the SMTP relay?

[Tech Support]

Certainly. Here's what you'll want to do:

1) Open the PG Admin.

2) Go to Connectors - Global - SMTP.

3) Put a check in "Relay All Mail"

4) In the Relay Server field, enter the IP, machine name or SMTP server address for your Exchange Server.

5) If authentication credentials are required, go to the Advanced sub-section of your SMTP based carriers.

6) In the Auth|Pass field, enter the username and password, separated by a pipe (which is shift + \ on your keyboard)
