You should also notice that in the /var/spool/hylafax/info file that 
corresponds to this destination that it is now marked 
"supportsBatching:no".  This should prevent it from sending in 
batch-mode again to that destination.  If you find that it repeatedly 
tries EOM to that destination afterwards, then there is a bug in your 
HylaFAX version.  (Try HylaFAX+ 5.2.7 if so.)

Batching support is part of ITU T.30 (the fax protocol standard).  
However, since it's a much less-frequently used feature, one that is not 
often ever employed by many fax machines when sending... it's a feature 
that isn't perfectly supported by all fax receivers.  So HylaFAX tries 
to detect these cases and avoid sending batches to them again.

Thanks,

Lee.
