sendmail, 4th Edition

-d2.1

End with finis( ) Debug command-line switch

Ordinarily, sendmail exits silently when it is done (unless an error causes an error message to be printed). The -d2.1 (a.k.a. -d2) debugging switch causes sendmail to print three useful values when it exits. The message it prints looks like this:

=  ==  =finis: stat number e_id=qid e_flags=flags

The number is the final value of the sendmail program’s global ExitStat variable. It is usually updated to contain the latest error value as defined in <sysexits.h >. See sendmail’s exit( ) Status on page 228 for a detailed description of the possible exit values.

The qid is either the queue identifier (such as g7PI04TK027759), or NOQUEUE if the message was never assigned an identifier (if it was never queued, for instance).

The flags is a hexadecimal representation of the possible envelope flags followed by a text representation of those flags in angle brackets with the leading EF_ removed. For example:

201003<OLDSTYLE,INQUEUE,GLOBALERRS,HAS_DF>

These are the envelope flags that were in effect with the current envelope when sendmail exited. The possible values are shown in Table 15-5.
