Hello,
Is the mailing list software smart enough to detect a prefix after "Re:", or would a couple of replies back and forth yield "[GPC] Re: [GPC] Re: [GPC] Re: [GPC] Problem"?
I suppose it's smart enough, but I haven't tested this.
Majordomo understands a "Re: [GPC]" and removes it. It does not understand "AW: [GPC]".
Also here I'm not sure. What I'd prefer personally in this case is to put both addresses, the given Reply-To and the list address, in the final Reply-To header, but I don't know if/how this can be achieved.
MJ2 leaves a reply-to set by the sender intact. It will only add the reply-to header if none is provided.
I'm copying this mail to Anja, perhaps she can tell more.
HTH,
Anja
