I switched from mail hoster. The from address from a cron job is created by postfix. This was something like: ce...@mail.example.com. My old provider accepted this, but the new one does not. He says that the RFC says that you should not accept emails with a non existing from address. Is this true?
I added in main.cf: myorigin = $mydomain Now the above becomes ce...@example.com. But to make it work I would need to a mailbox for every user: root, www, ftp, … With some cron versions you could use MAILFROM, but sadly this does not work on Debian. Is there a smart way to rewrite the from address for emails that send the output of a cron job? -- Cecil Westerhof
