Thank you for that post. It is very important, especially parts C and D, and I 100% agree with all that you have written. I also considered using a "more comprehensive solution" that you suggest, but similarly have no time to implement it. BTW, I have no problems with sending to Microsoft, or Yahoo, or any other big recipients, except Google. That's the only one that is problematic. Of course I fell into the usual t-online block for unknown servers, but this has been resolved pretty quickly. The problem with implementing this is that many companies use Google for hosting their mail, so it should be used not only for destinations at gmail.com, but also for various other domains - you have to first check if a MX for a given domain is at Google, and it must be done with an external script, as Postfix's destination-based transport choice cannot check for MX, it can only literally check for recipient's domain (there were requests on Postfix list about such feature, and Wietse explained why it would be hard/impossible to implement with current Postfix architecture). The smaller problem (but still a problem for me anyway) would be that the messages would not come "From:" my original address, but "From:" the "relay" address I set up at Gmail. BTW, as for your remark regarding Google requiring an account to access Postmaster Tools - I don't know if it's still possible, but at the time when I created my Google account (it was quite a few years ago), it was possible to create it without simultaneously creating a Gmail account - you could just enter any existing email when registering an account, and so I did, registering the account for very this "r...@rafa.eu.org" email address, and this is the account I use to access Postmaster tools. So basically my email address should be "known" for Google for years, yet it still sometimes refuses to accept mail from it (sometimes, as the problem is intermittent - sometimes mail gets through fine, but sometimes not). My "temporary" solution is what I already described - I keep a backup domain, rafa.krakow.pl (which is basically, from email point of view, just an alias for rafa.eu.org - all email sent to x...@rafa.krakow.pl goes to x...@rafa.eu.org, both are hosted on the same server) and resend the message from that domain when it doesn't get through to Google. From that alternate domain it usually does get through. As for more general topics in your email (ie. points C and D), I fully agree, as I already wrote. Thank you. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
