It is (slightly) possible that the error is an internal issue in maild, and this patch will log that info.
The patch changes 2 source files error_message.h and maild.c The patch is available at https://bitbucket.org/cmoraes/ossec/changeset/5f91e1eb8f3d *Note:* I do not suggest you run this patch on a production system. If possible install a test environment and use this patch.
