Freshly configured autoresponder for QMail mailbox does not work - it does not send replies.
Resource (or service template) of "QMail Hosting" resource type has activation parameter "Maximum Autoresponder invocations rate per day" is set to -1 since provider wanted to set it unlimited.
On autoresponder invocation the follwoing error could be found in
dovecot: deliver(email@example.com): msgid=: saved mail to INBOX autoresponder2: error in getting throttling delay for autoresponder 'autoresponders//148/', error code is -5
Incorrect value is propagated to QMail configuration file if negative or very high (greater than 32766) value is set in activation parameter "Maximum Autoresponder invocations rate per day" of Mail Hosting resource. Autoresponder incorrectly interprets this value and refuses to send reply message. The issue is acknowledged as POA-110912: "QMail autoresponder breaks if 'invocations rate' is set to 'Unlimited'".
The issue could be mitigated by setting some reasonable positive value as "Maximum Autoresponder invocations rate per day" activation parameter.
