Action

The mailx(1) program can usually recover from this error and delineate mail message boundaries correctly. Pay close attention to the message that might be truncated or combined with another message, and to all messages after that one. If a mail file becomes hopelessly corrupted, run it through a text editor to eliminate all Content-Length lines, and ensure that each message has a From (no colon) line for each message, preceded by a blank line.

To avoid mail file corruption, exit from mailtool(1) without saving changes when you are currently running mail(1) or mailx(1).
