New Year's Day is ready to learn the configuration of the Postfix mail server (especially anti-spam and viral scanning), and how to upgrade Sendmail to Postfix.
According to my experience, in all server configurations, the mail server is the most difficult. And the most complicated. The concept involved is also the most.
This complex thing has deeply attracted me.
The first edition of the PostgreSQL Chinese document is to translate the prawns in the National Day holiday. I hope that I can gain something on this New Year holiday.
