Tigase server offers support for XEP-0079: Advanced Message Processing (often abbreviated to AMP).
It is enabled by default but there are several configuration options that you may tweak.
Configuration of AMP is not very complex, but as it is implemented as a component in the Tigase server it does needs a few settings to get it right.
Here is a first, brief overview of the AMP configuration and later detailed explanation of each parameter.
'sess-man' {
amp () {
'amp-jid' = 'amp@your-domain.tld'
}
message (active: false) {}
msgoffline (active: false) {}
}
'amp-security-level' = 'STRICT'
