Vulnerabilities
- A spamtrap becomes tainted when a third party discovers what the spamtrap e-mail address is being used for. Once this occurs, the third party could target the spamtrap by maliciously sending email to it giving the third party some control over the automated process of what is being considered bulk unsolicited e-mail by the anti-spam system. However, they would be able to subscribe a spamtrap address to an email list only if that list would not use confirmed opt-in.
- Spammers using spamtrap addresses from their mailing lists as sender addresses can cause backscatter when a reply/DSN is sent to the spamtrap address.
- If the spammer put a spamtrap mailbox with many others in the TO or CC line, when any of that other people reply or forward the message, this address will be considered spam too.
- Many spamtrap addresses show up in search engine results, and anyone can write to these addresses without knowing that all mail will be caught as spam.
