I won't, and I'm definitely interested in specific suggestions, but of course there are other contributing factors to the problem. Are there better defaults we could be shipping Mailman with that would make the problem less severe without making automatic bounce processing useless? > > The other option I would suggest is that list owners start turning on > > personalization, in order to take advantage of VERP.

Part of setting up VERP is MTA specific, and there are instructions in README.POSTFIX and README.EXIM covering those MTAs. Once that's done, its a matter of setting the various VERP_* variables in mm_cfg.py to your tastes, and then turning on personalization (not full) in Non-Digest deliveries. The bigger question is what the impact of VERPing is on bandwidth and performance. Other than doing the math, I don't have much to add, except that I've started to enable it on most python.org lists and it doesn't seem to be a problem. -Barry _______________________________________________ Mailman-Developers mailing list [EMAIL PROTECTED] http://mail.python.org/mailman/listinfo/mailman-developers
