[exim] * at end of logline

Hello,

I'm sure I knew it once, but at this moment I cannot recall:

What is the asterisk at the end of a logline for?

2006-11-02 22:39:22 1GfkHC-0007TK-Du => test@??? R=mailbox_cyrus
T=mailbox_lmtp H=10.0.1.10 [10.0.1.10]
2006-11-02 22:39:22 1GfkBY-0005FL-Mr => test@??? R=mailbox_cyrus
T=mailbox_lmtp H=10.0.1.10 [10.0.1.10]*

Does it have to do with defered deliveries that have finally succeeded?

Regards
Marten
