Looking at this sequence:
[maria@meimei .local]$ ls -Zd share

ls: cannot access 'certificates': No such file or directory
[maria@meimei share]$ mkdir certificates

1. Tells me a "FILE transition rule" exists, yes?
Yes, because the file you created did not inherit the data_home_t
label from the parent directory.
(Some special applications that have specific SELinux knowledge can
request that a file be created with a specific context, but "mkdir"
does not do this.)
2. How to list existing "FILE transition rules"?
$ sesearch --type_trans --source unconfined_t --default home_cert_t
type_transition unconfined_t config_home_t:dir home_cert_t "certificates";
type_transition unconfined_t data_home_t:dir home_cert_t "certificates";
type_transition unconfined_t user_home_dir_t:dir home_cert_t ".cert";
type_transition unconfined_t user_home_dir_t:dir home_cert_t ".pki";
type_transition unconfined_t user_home_dir_t:dir home_cert_t "certificates";
3. Wouldn't it be advisable the files such as "rc"
files which a
user may create in their home directory and are well known
standard programs have "FILE transition rules" already in
Contexts for many well-known dotfiles do have them. But
fetchmail_home_t doesn't, at least in recent Fedora SELinux policy:
$ sesearch --type_trans --default fetchmail_home_t; echo END
Perhaps file an upstream enhancement request with your distro to add
the missing file transition rules for fetchmail?
