I am occasionally finding some strange characters in the log file. I have captured on entry that vi cannot handle. It simply won't go past this record. I suspect the issue is around 0347 in the record below. Any ideas how to prevent this from happening as it makes it difficult to find specific records in the log. vi is unable to delete the line with this issue.

Here is the corresponding postfix log entry:
maillog.8.gz:Jul 9 02:05:44 mail postfix/cleanup[37269]: 4gwpw76RcYz1qpcj: message-id=<91050691.1476946.1783587935766@marketo-platform--email-sender-prod-batch-cluster-545fbbd7dmnt5>
Is it possible that the message_id field might be too long?
