Ive got 27 domains running on a single IP. Alle these domains send out notification emails (kinda like forum notifications) from email@example.com. (note : domain name changes depending on which domain is sending mail)
In some cases the email is rejected as the receipient server will try asking my server if the sender email is a valid email address (which its not).
Id like to create it into a valid email address, (so that my emails sent are not rejected) so I can receieve emails on the "donotreply" account, but the emails should be deleted and not stored.
Im using sendmail+PHP to send mails with. Any suggestions on if the above is possible and how?
I'd like to know how others are handling this too. Right now, we use a noreply mailbox. We treat it as if it were a bulk mailbox. It is monitored regularly as we have many users who just don't understand the concept of "noreply" even though we include a message in the email about not replying and to use the online Q&A section for their comments.
Not sure if this can be done at the website level, but I believe you can send emails for specific accounts like firstname.lastname@example.org through to null (i.e it gets dumped). You'd do this through postfix or sendmail though.
