Using honeypots to catch spammers?

I'd like to know how you think about honeypots?
Mail addresses that appear hidden on your websites and are used only by spammers.
If someone writes to the address, the IP is automatically banned.
Do you use such a solution? :?:

Thanks for the hint. I'll set it up that way too. :D

Re: Hacking

The spammer is already registered in the IP ranges in various lists. In the next step he would probably get stuck in the spam filter. Greylisting also makes sense for him because he does not send the mails repeatedly. https://mxtoolbox.com/SuperTool.aspx?action=blacklist%3a193.32.160.139&run=toolpag...

Re: Hacking

Don't get nervous :shock:
The spammer simply tries to send mails to various (non-existent) recipients. They are rejected with status "550 Unknown User".
It is daily routine!

You don't need to ban the ip-range.

Re: hMailServer 5.7

Conclusion after almost 5 days in productive use. 5.7 works just as stable and reliable as the 5.6.8.

Re: External POP3 Fetcher - DELE without RETR - crashing frequently

I haven't found the cause yet. So far everything runs very stable and there are no problems to retrieve the mails. After I had problems, I went back to version 5.6.8. Since Martin created new builds for 5.7, I dared to do it again. What do you want me to say? It's on. :) Probably it's really related...

@derelvis Thank you for your feedback!

Re: External POP3 Fetcher - DELE without RETR - crashing frequently

I've tested the 64bit build 5.7.0-B2469 (on a Windows Server 2016 machine) and got problems with fetching from external pop3 accounts. Also an error on Diagnostics in part 'Test outbound port', tls or so? Switched fast to the latest 32bit build and all is fine again. Sorry, but I deleted all logs an...
