Today I sent out a blast using a distribution on open source version
Version 6.0.10_GA_2692.FOSS Dec 15, 2010.
The list is marked allowing it to "receive mail". When someone responded to my mail I got they got this crazy prompt on their screen and it just vanished. Lucky for me he grabbed it in time and send it to me..... posted here.
I am not sure why they should get a log in prompt when responding to a distribution list mailing - none of the participants have accounts on the server.
Has anyone seen this before and have a fix?
