QuickFinder Indexing gives error "F041" while indexing a comma delimited txt file larger than 20 MB

Post office Agent throws out error "F041" while indexing an email having a comma delimited text file more than 20 MB as an attachment.
Error "F041" does not occur during Post Office Agent indexing, if the file is removed from the attachment

The error F041 refers to such problems as a document containing the same word too many times.  It is reasonable, when word indexing documents, to have reasonable limits that can keep index files to a reasonable size.  In other words, if the only thing seen was a log entry indicating an error that a particular message could not be word indexed, and indexing continued normally, we would not consider that to be a problem.
