Message from ” exceeded the maximum hop count(). The archive filename is ”.

Product: Exchange
Event ID: 12070
Source: POP3SVC
Version: 6.5.6940.0
Component: Microsoft Exchange POP3 Service
Message: Message <message id> from ‘<host name>‘ exceeded the maximum hop count(<value>). The archive filename is ‘<file name>‘.

This event indicates that the maximum number of hops permitted has been reached. This limit is set at the Simple Mail Transfer Protocol (SMTP) Virtual Server level in Exchange Server.
Messages can travel through several SMTP servers before reaching the virtual server. Each time this occurs, the intermediary SMTP server adds a line of text, that references the hop, to the message’s header. The default maximum number of hops is 15, although the optimal
number may vary depending on the topology of your network. When a message reaches the SMTP component of an Exchange server, the hop count on the message is compared with
the MAXIMUM HOP COUNT set on the SMTP Virtual Server Properties of that Exchange server. If the hop count on the message exceeds the MAXIMUM HOP COUNT set for the particular SMTP Virtual Server, the message is rejected.
