Except DJB's software was often not right (Qmail was a major offender against SMTP protocol specification for a long time, until it finally got forgotten by most of the sysadmins) or otherwise sub-par (djbdns lacked sensible zone transfers, even non-incremental ones).

Qmail is an offender against smtp protocol specs? New one on me, still using it and it works well. Zone transfers? Moving data is best done by other unix utilities, not monolithic programs like bind.

  > Qmail is an offender against smtp protocol specs? New one on me, You must be using it for several years at most. In the old(ish) times, when there were just Exim 3, Postfix, Qmail, and Sendmail, Qmail was getting quite large flak from mail admins on various forums and newsgroups. Now, not so much, but not because it got better (it didn't), but virtually nobody uses it anymore. > Zone transfers? Moving data is best done by other unix utilities, not monolithic programs like bind. Oh yes, certainly. Let's do the same to replication in databases and directory services (like LDAP).

> Qmail was a major offender against SMTP protocol specification for a long time No, it wasn't, ever. It is OK to offer an opinionated view of, e.g., qmail, but please stick to facts. Some people used to argue that qmail's single recipient per envelope was some kind of violation. It never was, still isn't, so please don't repeat flame wars of the 1990's. djbdns didn't provide zone transfers because they were a crappy way to achieve the desired effect and reduced the reliability of the service. Even at the time djbdns was published it was not best practice to enable zone transfers on production servers. No one today uses it for systems that have to be reliable and scalable.
