Not so. By doing nothing (ie NOT creating an SPF record for the sending domain) you pretty much guarantee a lack of problems. (At least, these specific problems). It's the smart aleck admins who do create SPF records etc who cause the problems, in conjunction with recipients that think these records are worth paying attention to. The irony is that SPF was invented by the advertising industry to ensure that their so called 'legitimate' bulk mail gets through; it does very little to stop actual spam and it completely messes up mailing lists and people who use traditional SMTP mail while travelling. Sorry, I shouldn't start on SPF, it just drives me crazy. If you are a DNS admin, *please* don't fall for the SPF bullshit. (For some reason Microsoft are totally enamored of it and twist their clients' arms to enable it :-/ )
You are preaching to the choir. Some of the first implementers of SPFs were outfits that the rest of us would call spammers. As for Micro$oft, my employer trashed our Zimbra and PMDF servers and sent us over to Office365 so now I spend my time babysitting Exchange in the cloud, writing PowerShell scripts, and waiting a Micro$oft minute for things to happen that used to be immediate. And you are right, Micro$ofts loves SPFs but they do nothing at all to expedite our mail through their servers. And in honour of Micro$oft, SPFs, and my 21st century managers, I am retiring in 29 days. -- Richard Loken VE6BSV, Systems Programmer - VMS : "...underneath those Athabasca University : tuques we wear, our Athabasca, Alberta Canada : heads are naked!" ** [email protected] ** : - Arthur Black
