Then add maildrop to replace the original MDA ~ Google many ways

Extmail then provides the filtering function, automatic reply, and blacklist and whitelist.

Maildrop has its own syntax structure, such as xfilter "PHP-f. PHP "to call external programs, written in. in the mailfilter file, control the calling of certain programs when receiving emails, or filter and reply emails. Of course, MDA also has other alternatives.

It is important to set permissions during server setup. Otherwise, errors may occur frequently. Some problems may occur due to the lack of a module.

Courier-authlib is used for maildrop persistent layer access.
