So what happens when I set up everything but the sender of an email which
should be accepted by one's MTA has no such record?
I could imagine that this happens now and for the next month in about more
than 90 percent of all mail which is received by one's MTA.
Sure, one solution would be just to provide the records and not using it on
MTA side, but one day you should use it (IMHO asap) and you can't be sure
that all senders are providing it at this time.
Seems like a chicken-egg-problem...
I guess you can start to use SPF in an incremental way. At my new
workplace the mailserver just adds an additional header entry to
incoming mails and users are free to do with that whatever they want:
Received-SPF: pass (seems reasonable for [EMAIL PROTECTED] to mail
through xxx.xxx.xxx.xxx) client_ip=xxx.xxx.xxx.xxx
envelope-from=<[EMAIL PROTECTED]> receiver=cse.unsw.edu.au
I am free to refuse mails when an SPF-pass is missing, I can use it to
add some score to a mail or I can completely ignore it (as I do for now...)
