Thanks Jasen. Nice solution. I had found one using a local variable, but this one is cleaner and better. I'll use it.

[exim] Subject rewriting
Hi, I need to change the subject when the message is considered as spam, *and* when there is an SPF problem. I use the following method: 1 - for SPF: # remove old subject remove_header=Subject # create a new subject add_header = Subject: *** SPF Error *** $rh_Subject: 2 - for SPAM: # remove old subject remove_header=Subject # create a new subject add_header = Subject: ***SPAM (score: $spam_score)*** $rh_Subject: It works fine when either of these two cases occur. But when both occur at the same time, I don't get the expected result. In this case, I get two "Subject" headers. Is there a way to have a subject like: Subject: ***SPAM (score: $spam_score)*** *** SPF Error *** xx xxx being the original subject Furthermore, would it be better to use $h_header? Thanks in advance for any idea. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
