Re: any api to read logs ?

If I were to depart from the unstructured text syslog format, I'd shift to CSV; with a reasonable choice of quoting rules it can robustly round-trip a lot of tabular data, and very fast writers and parsers are available. I, personally, wouldn't find a more complex structure that easily represents

Re: server hw sizing

Can I do this with Postfix? Equal prioritization of email delivery from different users
