Topic: Are user id extensions (suffixes) supported?

[adamf663]

An antispam tactic I use is to add an extension to my userid when supplying it on web forms.  For example, userid@domain.com could become userid+iknowyou@domain.com.

The email system would then ignore the extension and deliver emails to userid@iknowyou@domain.com to userid@domain.com.
If the user starts getting spam, he can then see the +iknowyou extension and know who the culprit was who passed his userid on to the spammers.

I don't see this feature in smeserver.  Does the feature have another name other than "suffix" or "extension"?

I think you will have a waste of time trying to track down the spammers.

How ever, SME Server does allow the use of

userid-iknowyou@domain.com

With SME server, you can use:

userid-iknowyou@domain.com

[Note that there is currently an open bug, because this works only for users, and not for groups:

That'll work.

I don't expect to track down spammers other than know that the website I gave the alias to can't be trusted.
The other thing I can do is add an email filter on the alias to block it;  problem is of course with spammers that strip it.  Using minus instead of plus is less conventional and will be more resistant to spammers stripping the extension.
