this may seem incoherent, as I am fiddling with things I know little about....
I'm setting up my list on a new machine & new internet connection. It is very close to all working. Problem is I am on a dynamic COMCAST business class address, and I want to relay email through my COMCAST business server. All works, except that their server will bounce email which doesn't have a "proper" from address. (for those curious, I use DYNDNS service in case my ip changes, but my experience with COMCAST is that won't happen much if at all)
Most messages, especially outgoing list messages have valid outgoing from addresses. Problem arises with administrative messages LISTSERV sends to other LISTSERV machines, or in response to requests. Here is an example from my mail log of an administrative outgoing email. This one worked because I relayed it via a server which doesn't refuse these empty paths, but I prefer not to use that relay as I'd need to throttle outgoing messages considerably:

Nov 7 12:33:52 vetprofhomeipnet postfix/qmgr[986]: 0971439AEBB3: from=<>, size=1733, nrcpt=1 (queue active)Nov 7 12:33:52 vetprofhomeipnet postfix/smtp[1081]: 0971439AEBB3: to=<[log in to unmask]>, relay=vetprof.com[184.173.206.127]:25, delay=0.81, delays=0.01/0.01/0.67/0.11, dsn=2.0.0, status=sent (250 OK id=1TWCJs-0002qr-Og)

COMCAST's smtp refuses to accept the empty <>. Example:
---
Nov 7 12:59:24 vetprofhomeipnet postfix/qmgr[1444]: AABD039AEC09: from=<>, size=1733, nrcpt=1 (queue active)
Nov 7 12:59:25 vetprofhomeipnet postfix/smtp[1509]: AABD039AEC09: to=<[log in to unmask]>, relay=smtp.ch3.comcast.net[76.96.107.76]:25, delay=0.66, delays=0/0.01/0.5/0.14, dsn=5.1.0, status=bounced (host smtp.ch3.comcast.net[76.96.107.76] said: 550 5.1.0 <> sender rejected: invalid sender domain (in reply to MAIL FROM command))

It is interesting how the actual message *does* contain a From: header, but an empty <> ! I'm appending that message for those interested.
I understand from Eric Thomas that such messages with no return path are part of LISTSERV's dealing with issues it doesn't need to worrry about - i.e. a bounce of such a message is not something listserv can do anything with, so no need to have a return path. However, I want to relay via COMCAST and I need *something* in the return path.
Does anyone know how to have LISTSERV insert something in the empty <> for outgoing administrative messages? I'd be fine with <[log in to unmask]>. I'd create that account or alias for real bounce handling in a heartbeat. I just want to make the COMCAST server happy.
Thanks, Jeff Parke
