I tend to suspect this as well, this is when I see 1 or 2 consecutive
errors from the sender and then a successful fax after. Or sometimes 3
successful faxes where the first 2 get interupted. Either way a I am
more interested in the ones that connect 20 times and fail 20 times.

I keep that extra option, it did decrease the amount of errors. I
noticed also that some of the errors that I see in the log directory
do not get reported as an emil to FaxMaster. This is pretty important
to me as I can make some sense out of these errors. Such as I scan the
ALL the log files (using grep) to see how many times a certain TSI
sent me a fax sucessfuly and how many time they failed. I also log the
error type and date too (I don't think I get this kind of stats with
faxcron.) This helps me know that if a certain sender has previously
sent me a successful fax then I can ignore the logs where they got
Modem Command error or time outs, I can rule those out. But for the
ones that have a 100% rate of failure is the ones I can focus on.
Perhaps this can be put into faxcron at a future time ? :)
