These effectively 'clean up' the retry, reject, and wait_remote_smtp db when
called. That is normally a periodically scheduled event anyway, so no harm.

The courier call may be a POP/IMAP rehup, daemon and/or Courier's webmail.
You'd have to check the entries in each of the scripts called to be sure:
less /scripts/courierup
less /scripts/eximup

You are effectively giving Exim a case of temporary amnesia and sending it back
to school to relearn - ahead of schedule.

No bad effects should be expected.

Hadn't noticed.
BTW - the scripts you cite are probably a local or OS/distro inheritance - built
to make use of documented Exim controls, but not themselves ordinarily a part of
the Exim 'package' (AFAIK), so probably not covered directly in the main Exim docs.
You might have a look in the examples, or if a Linux, especially Debian or
derivatives, at the specific docs which that team will have supplied with their
modified distro. That may not apply here, as that team call Exim 'Exim4' and you
have not mentioned that identity.
