This would require a custom filter that search for the line "subject:" during the DATA transfer. I will write one when I have some free time. -fred -------------------- You + webcam - clothes - dignity = $

I use the following with mailing list to include list name in subject, because I didn't find any option in XMail to do it automatically (I hope I didn't just overlook it

.

It's tested on Linux only.

It rewrites:

QUOTE

Subject: some subject

to:

QUOTE

Subject: [mylist] some subject

or does nothing if the identifier is already present, for example in:

QUOTE

Subject: Re: [mylist] some subject

I use it for outgoing mail sent from the list address:

filters/listsubj-mylist:

QUOTE

"/opt/xmail/bin/listsubj-filter" "[mylist]" "$(FILE)"

filters.out.tab:

QUOTE

"mylist@example.net" "*" "::/0" "::/0" "listsubj-mylist"

But now when I think about it, putting it in filter.in.tab for everything sent _to_ list address would probably be better, because it would be run only once for each mail. Doesn't really matter for me, I have only few subscribers anyway.

listsubj-filter.c:

QUOTE

#include <stdio.h>
#include <string.h>
#include <unistd.h>
#include <stdlib.h>
#include <errno.h>

void fail(char *msg, int code) {
//printf("FAIL: %s\n", msg);
exit(code);
}

int main(int iArgCount, char *pszArgs[]) {
FILE *fdata, *fmail;
char line[1024];
char tmp[1024];
char mailfile[]="/tmp/lsfilter_XXXXXX";
char separator[]="<<MAIL-DATA>>";
int header=1;
int rewritten=0;
char *p;
int fd = -1;

if(iArgCount!=3) fail("usage: listsubj-filter <prefix> <message file>", 0);
if((fdata=fopen(pszArgs[2], "r+"))==NULL) fail("Can't open input file", 0);
if((fd=mkstemp(mailfile))<0) fail("Can't create mail temporary file", 0);
if((fmail=fdopen(fd, "w+"))==NULL) {
unlink(mailfile);
close(fd);
fail("Can't open mail temporary file", 0);
}
//
while(fgets(line, sizeof(line), fdata)) {
if(!header && !rewritten) {
if(strncmp(line, "Subject:", 8)==0) {
p=strstr(line, pszArgs[1]);
if(p) {
fclose(fmail);
fclose(fdata);
unlink(mailfile);
exit(0);
} else {
sprintf(tmp, "Subject: %s", pszArgs[1]);
strcat(tmp, line+8);
strcpy(line, tmp);
rewritten=1;
}
}
}
fputs(line, fmail);
if(header && strncmp(line, separator, sizeof(separator)-1)==0) {
header=0;
}
}
//
fseek(fmail, 0, 0);
fseek(fdata, 0, 0);
while(fgets(line, sizeof(line), fmail)) {
fputs(line, fdata);
}
fclose(fmail);
fclose(fdata);
unlink(mailfile);
//
exit(7);
}

Compile with:

QUOTE

gcc -o listsubj-filter listsubj-filter.c
