Hi Duncan, > The "vacation" message never makes it to the list (I understand this is > normal)
Yes, that's correct. I'm sure you don't want vacation messages distributed through the mailing list. :-) > and any postings to the list never make it to the person with > their "vacation" autoresponsder set up. That's bad, without question. > deferral: AUTORESPOND:_I_can't_handle_a_message_with_a_Mailing-List_header I often noticed the autoresponder doing stupid things. In case of "I can't handle a message with a Mailing-List header" I suggest it should exit silently with an error code of 0 instead of 100 because... * 100 prevents the message from being delivered to the final recipient * Nobody is interested in getting informed about a vacation message that hasn't been created Anyway, I wonder why your log notes this line as "deferral". Judging from the source (I have autoresponder 2.0.3) it exits with 100 which means "hard error" = "failure", while only 111 should generate deferrals. Hopefully somebody can bring some more light into this. I guess the autoresponder's exit codes need some additional review. Jonas
