In order to scan mailboxes for invalid messages you will have to use the CLI interface. In order to connect to the CLI interface you can use telnet:

telnet <Axigen IP address> 7000

<login> user admin

<password> qwe123

For a list of available commands, type HELP

+OK: Authentication successful

<#>

Then enter the domain context:

UPDATE Domain name <domainName>

+OK: command successful

<domain#>

Now use the FINDINVALIDMSG command in order to scan for faulty messages. The usage of this command is:

FINDINVALIDMSG <accountName> [<accountName>...] [purge] - list and optionally remove faulty messages from specified accounts

For example, if you need to search mailboxes for user1@<domainName> and user2@<domainName> you will have to issue:

<domain#> FINDINVALIDMSG user1 user2

Note: You can add the optional purge which will remove faulty messages if found.
