Martin Tomes (mt00@eurotherm.co.uk) asked me about a problem he is having: [Martin] | We are on some mailing lists and by the time messages get to us they | have passed though many machines and the hop count is high, we then | bounce the message and Joe Stoy at Oxford gets them and wishes he | didn't. Is there a way to persuade sendmail to allow more hops? The | memximum appears to be 17. It is sendmail on an Ultrix Decstation | which is bouncing the messages. I discovered this problem with Sun sendmail a couple of years ago and cured it using the (undocumented?) Oh configuration option i.e. Oh30 added to the config file set MAXHOP to 30. Unfortunately it doesn't seem to be supported by Ultrix sendmail. I suppose it might be possible to use the -h flag on the command line to reset the hop count when the message arrives. This presumes that you have the source for an interface program between whatever transport system you used to take mail into the site and sendmail (i.e. rmail.c as supplied with UKsendmail). I've never tried this but assuming it *does* reset the hop count, overriding the number of Received: lines in the message header, then it should work. It would mean problems if a message was bouncing between you and an outside site however - it would bounce forever. Perhaps it would be possible to check that the message hadn't already been through your site by looking through the Received: lines and only resetting the hop count if it hadn't. Does anyone have any comments on this or any better solutions (like where he could poke the sendmail binary with adb)? --- Support Desk: Two, four, six, eight Who do we appreciate? DESK! ---

What I would recommend you do is to fetch the latest source version of 5.65+IDA sendmail, ready ported to Ultrix, from gatekeeper.dec.com.

Righto. IDA-1.4.3 should be called UIUC-1.4.3. We don't use it here.
