Re: [Nmh-workers] 1.1rc3 - add rfc3461 DSN support

Hi Valdis,

Just some complaints about the patch.  Feel free to ignore as you'd made
the effort and I haven't  :-)

I'd hate to see NULLCP, NULLIP, etc., make an appearance.  The above
would seem less noisy as

    if ((ret || envid) && EHLOset("DSN")) {
        if (ret) {
            if (strlen(ret) > 8) ret[8] = '\0';
            sprintf(tmpstr, " RET=%s", ret);
        }
        if (envid) {
            if (strlen(envid) > 100) envid[100] = '\0';
            strcat(tmpstr, " ENVID=");
            strcat(tmpstr, envid);
        }
    }

Also,

    switch (smtalk (SM_MAIL, "%s FROM:<%s>%s", smtpcom, from,
        tmpstr ? tmpstr : "")) {

is checking tmpstr which will always be true.  Given *tmpstr is
initialised to 0 it may as well me just

    switch (smtalk(SM_MAIL, "%s FROM:<%s>%s", smtpcom, from, tmpstr)) {

This occurs elsewhere in the patch too.

Need these have an explicit notification?

Cheers,


Ralph.
