tvScience Hosting - Timeout Addresses.

As a service to our clients we offer a special range of time-limited email addresses like the following:

• enquiry-NNNN@example.com
• mail-NNNN@example.com
• reply-NNNN@example.com
• subscription-NNNN@example.com
• news-NNNN@example.com
• NNNN-enquiry@example.com
• NNNN-mail@example.com
• NNNN-subscription@example.com
• NNNN-news@example.com

To use, replace NNNN with today's date in any of the following formats: YYYYMMDD, YYYYMM or YYYY, These are vaild for a limited time only. After that, mail bounces with a "Out of date address" error.

Each can be forwarded to any destination as with other email routing. Once set-up, no further action is needed as the rollover is automatic.

These are useful as an anti-SPAM measure in any of the following circumstances:

• For "mailto:enquiry-2025@example.com" links on webpages. You'll need to update these by hand or use a scripted page (see below).
• When posting an email adddress to newsgroups or in chatrooms.
• When subscribing to an email-based newsletter service.

In all the above you may only want to accept replies for a limited time and not be bombarded by SPAM for years in the future. This facility is ideal for this.

There is a grace period after any particular date's expiry.

Examples:

The examples below are produced from today's date of 25–10–2025:

• enquiry-2025@example.com or 2025-enquiry@example.com are both valid between December 2024 and March 2026.
• mail-2026@example.com will be valid between December 2025 and March 2027.
• reply-202510@example.com is valid for October and November 2025.
• news-20251025@example.com is valid for today and tomorrow only.

An alert spammer could easily deduce the currently valid addresses. This has never happened.
