Hi

I am currently involved in helping to specify an e-mail delivery system for a client, and am finding it difficult to find information on how to detect hard & soft bounces of e-mails.

Does anyone have any information on:

• How to detect soft bounces such as: Out of office replies, mailbox full, auto-responders etc.
• How to detect hard bounces such as: Mail account no longer exists, domain invalid, mail server unavailable etc.
• How to deal with the various e-mail responses that mail servers use, especially considering a message such as "Mailbox full" works well for English, but this will not work for other languages.
• Is there a consistent header / error number that can be identified in mail server responses for these bounces?

Any advice on how to find this information, if there are open source tools, 3rd party tools available etc. would certainly be appreciated?

Regards,

Matthew O’Riordan
