Hello_World

Hello

I want to hide OPenDKIM version as my client does not want to show in emails for some reason.

DKIM-Filter: OpenDKIM Filter v2.11.0 server.domain.com 3506081C66

He only wants to disable v2.11.0 from end.

Thank You for help in Advance.

Instead of trying to customize it, may be you can skip addition of entire "DKIM-Filter:" header by putting:

SoftwareHeader false

in your "/etc/opendkim.conf" file?

Hello_World

sed -i 's/SoftwareHeader yes/SoftwareHeader no/' /etc/opendkim.conf

This is part of shell script. I have already did this thing.

You cant only remove the version and keep the rest (without recompiling your own little edits), but as @akb said you can disable the full message.

If you are interested here is the source for the specific part that sets

    if (conf->conf_addswhdr)
   {
           char xfhdr[DKIM_MAXHEADER + 1];
           
           memset(xfhdr, '\0', sizeof xfhdr);
           
           snprintf(xfhdr, DKIM_MAXHEADER, "%s%s v%s %s %s",
                    cc->cctx_noleadspc ? " " : "",
                   DKIMF_PRODUCT, VERSION, hostname,
                    dfc->mctx_jobid != NULL ? dfc->mctx_jobid
                                            : (u_char *) JOBIDUNKNOWN);
            ......

@Hello_World said: sed -i 's/SoftwareHeader yes/SoftwareHeader no/' /etc/opendkim.conf

Make sure its uncommented that line (remove the #) and then restart OpenDKIM
