-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 Section 15.5 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 16-6.

Text	Hex	Description
EF_OLDSTYLE	`0x00000001`	Use spaces (not commas) in headers
EF_INQUEUE	`0x00000002`	This message is fully queued
EF_NO_BODY_RETN	`0x00000004`	Omit message body on error
EF_CLRQUEUE	`0x00000008`	Disk copy is no longer needed
EF_SENDRECEIPT	`0x00000010`	Send a return receipt
EF_FATALERRS	`0x00000020`	Fatal errors occurred
EF_DELETE_BCC	`0x00000040`	Delete `Bcc:` headers entirely
EF_RESPONSE	`0x00000080`	This is an error or return receipt
EF_RESENT	`0x00000100`	This message is being forwarded
EF_VRFYONLY	`0x00000200`	Verify only (don't expand aliases)
EF_WARNING	`0x00000400`	Warning message has been sent
EF_QUEUERUN	`0x00000800`	This envelope is from the queue
EF_GLOBALERRS	`0x00001000`	Treat errors as global
EF_PM_NOTIFY	`0x00002000`	Send return mail to postmaster
EF_METOO	`0x00004000`	Send to me too
EF_LOGSENDER	`0x00008000`	Need to log the sender
EF_NORECEIPT	`0x00010000`	Suppress all return receipts
EF_HAS8BIT	`0x00020000`	Has at least one 8-bit character in body
EF_NL_NOT_EOL	`0x00040000`	Don't accept raw newline as end-of-line
EF_CRLF_NOT_EOL	`0x00080000`	Don't accept carriage-return/line-feed as end-of-line
EF_RET_PARAM	`0x00100000`	SMTP RCPT command had RET argument
EF_HAS_DF	`0x00200000`	Set when the df file is instantiated
EF_IS_MIME	`0x00400000`	This is really a MIME message
EF_DONT_MIME	`0x00800000`	This message is not MIME-able
EF_DISCARD	`0x01000000`	Discard this message
EF_TOOBIG	`0x02000000`	This message's body is too big
EF_SPLIT	`0x04000000`	This envelope has been split
EF_UNSAFE	`0x08000000`	Message read from an untrusted source

For example, if the message were fully queued and required a DSN return receipt, the flags would print as:

e_flags=12<INQUEUE,SENDRECEIPT>

Note that this line of output is also produced by the -d13.1, -d40.3, and -d50.1 debugging switches but under different circumstances.
