Yes, I use capi4hylafax. Just tried to read the sources and I don't
think it's possible for me right now, to alter them in any manner
that wouldn't render them totally unusable :).

Well, it's an ISDN AVM C4 card with four lines (2 attached, actually).

Currently I'm trying to make hylafax actually accept the parameters
setting retry delay after different kinds of failures, but it just
doesn't seem to work, I wonder if it's because of hylafax, capi4hylafax,
or maybe it's just me and my misunderstanding of the documentation.

Even sending the fax with:

sendfax -n -I '3600' -d somenumber _file_

does not affect the SLEEP FOR 4:31 (this seems to be a random time
within the limit of 3-8 minutes or so, but since I use a switch to
make it 1 hour, something must be wrong). 

All I can come up with now is that I will have to parse the log files
to detect the jobs that failed with a message like:

SEND INCOMPLETE: requeue for 4:37; An error occured while trying to
establish the connection.

(as when they fail due to a busy signal detected, the message is
different of course) and remove the jobs with faxrm. But this sounds
soooo wrong.

Does anyone have at least a little less ugly idea?
