Identify emails on a server.

[hack3rcon]

Hello.
I used "The Harvester" tool for finding emails on a server and this tool found some addresses but they are not OK and when I sent email to those address all emails failed. Can any tool on remote server trick "The Harvester" ? How can I understanding that emails are real?

Tnx.

i see you never took to the advice we gave you here: https://evilzone.org/hacking-and-security/email-harvesting-21769/msg112745/#msg112745

Now to answer your question, are the harvested Emails in the correct format? Read up on this RFC, they can be fun sometime: https://tools.ietf.org/html/rfc2822 or the wikipedia page before you continue.

If it is the format that is wrong, then i blame you for not following our advice in the linked post you posted this.

If they are in the correct format, then 'The harvester' wasn't fooled it got you your emails alright, they are damn not active for some reason. Again, get a test page, look through it manually and see if the tool got you alright, then conclude who of the both of you is dumb.

Otherwise, this ain't no different from the previous question you asked?

Maybe try asking the developer:

A site could add fake emails in the meta to mess with harvester.

Harvester Killer - help fight spam!

Anti-Spam Bots!This page shows a 100 randomly generated email addresses. Email harvesters (also known as spambots) will crawl this page and store all of these hundred bogus email addresses in a database, and follow the link at the bottom of the page, filling them up with more invalid email addresses as they go along. They eventually end up in an infinite loop, and thousands of randomly generated email addresses before the spammer realises what's happening.

Put in the following code in your webpage:
<A HREF="http://www.spamhelp.org/harvesterkiller/">Anti-Spam Bots!</A>

or

<A HREF="http://www.spamhelp.org/harvesterkiller/"><IMG SRC="http://www.spamhelp.org/harvesterkiller/harvesterkiller.gif" border="0" width="88" height="31" alt="Anti-Spam Bots!"></A>

You may also host the image on your server and linking to the image directly on your server.

Why Harvester Killer?
We believe that using anti-spam software or anti-spam appliances to filter out spam is not enough. While spam filters may help you from getting spam emails, they still waste your bandwidth, or your server's bandwith. Harvester Killer helps fight spam from its roots by discouraging the spammers in a direct attack at UBE (Unsolicited Bulk Email) and UCE (Unsolicited Commercial Email).

I guess you right. They can trick Harvester with adding some data.Can I identity emails addresses via telnet to server or something like it?
