Do you accept wildcards, or create a new alias in advance every time? I used to accept wildcards around turn of millenium but spam was overwhelming.

How do you stop "mainstream" providers from sending your emails to spam?

I do not accept (and never have accepted) wildcards. I create a new alias in advance every time.

I use the ISP's server for sending, and use my own server for receiving (the menu for install Exim has a "smart host" option which does this).
