AMETHYST admin log: ...unable to rely for...

[Belinda Frick]

If there is a problem when AMETHYST sends an e-mail it will list the
e-mail address of the recipiant and the entry "unable to rely for".

If critical e-mails is present in the logs, but not received and there
is no "unable to rely" entry in the admin log then AMETHYST sent the
e-mail, but it was blocked thereafter.
