I've tried to send to following mail to [email protected], but it bounced.
Since this is a violation of RFC5321 this is an even more serious issue than the two I point out in my mail, please fix this ASAP.<[email protected]>: host adafruit.com[207.58.139.247] said: 550 No Such User Here" (in reply to RCPT TO command)
Given I can not currently receive mails (and therefore forum notifications) from your mail server, please send any questions directly to [email protected].

Hi,
I've just registered and filled out the notification form for an item on
adafruit.com, but neither confirmation mail did get through.
1) I've noticed that you use 207.58.139.246 as your mail server, but the
rDNS isn't set up properly. 207.58.139.246 points to vps.ladyada.net,
but vps.ladyada.net doesn't have an A record pointing back to
207.58.139.246. If you want to ensure that mail coming from your systems
will be delivered, please set up a proper forward confirmed rDNS.
For more information please refer to wikipedia:
https://en.wikipedia.org/wiki/Forward-c ... everse_DNS
2) I have also noticed that you use [email protected] as the
sender address for your web shop and I'm assuming that mails sent to
this address are deleted automatically. I highly recommend that you use
an address that will be monitored by someone since I don't think it's in
your interest to loose potential clients because of mail delivery
problems which go unnoticed because bounces are ignored.
If you are not responsible for the web shop's configuration, please
forward this mail.
If you have any questions, please make sure to reply to
[email protected] until the rDNS problem is fixed.
Best Regards,
Florian
