I think I've found the problem - comments below.

The issue here is that crm_mon.c uses smtp_set_reverse_path(), which 
expects only a mailbox name, e.g. 'ClusterMonitor at example.com'.  It does 
not appear to accept other variants, such as 'Cluster Monitor 
<ClusterMonitor at example.com>'; doing that results in the entire 
--mail-from argument being interpreted within angle brackets, which 
turns 'Cluster Monitor <ClusterMonitor at example.com>' into <'Cluster 
Monitor' <ClusterMonitor at example.com>'>, which is a malformed sender 

Would the devs find it reasonable to accept a patch that uses something 
like regcomp() to check and see if the argument provided already 
contains a 'From: ', and if so, uses smtp_set_header() instead of 
smtp_set_reverse_path()?  That would maintain backwards compatibility 
with the current style & give one the ability to form more complex From: 
addresses, since smtp_set_header() is passed through unchanged.
