I am currently looking to create a reverse DNS entry but our mail server is based on a home network connected a 10gb/s (yes I know it’s not common for a home network but yeah…) I am not willing to move it to a VM in a data center or even the dedi that hosts our website.
So I was wondering if it’s possible to create a Reverse DNS (PTR) record easily (i saw things with bind9 but I simply want 1 DNS record).
Is there any way to do it I googled it but yeah… it’s not very effective of course I take any links!
Thanks for your help c:!
Do you own your IP? If not, work with your DC
As @SERIESN says, unless you own the IP you might not be able to adjust the PTR record for it from your name servers.
If it’s a business ISP they should let you change it - my home ISP allows me to set the PTR record for my IP.
If it’s about delivery of mail, you could relay through a VPS which has a PTR record set, without moving the whole mail server - or relay through SES/Mailchannels/etc.
So let me guess.
salt in north of ch maybe zrh
If such is the case it makes me jealous
My wild guess it’s that it’s residential.
If its Salt, they would need to set the rDNS, i doubt that they will do that.
Swisscom does offer it if you have a Business Line.
And as @Mr_Tom said, a relay over a VPS might be a good idea or moving it to a DC to improve Uptime and Stability;)
Surely if a residential ISP is willing to give you 10G they’d also be able to provide rDNS So I’d say contact them
Thanks for all your replies.
I will try to contact my ISP.
I don’t want to move this R720XD because it’s really pretty useful at my brothers home. We have full redudancy with a few UPS and we have 2 servers in it one is not one of ours so yeah… It’s mainly network uptime i guess XD
But yeah i hesitate to switch totally the mail system to the DC.
And there is no need to. As @Mr_Tom indicated it is quite possible, and rather easy to relay via a VPS which would indeed have the ability to properly set a PTR record.
You could even set it up so that ONLY the outgoing email goes through the relay … just in case that eases some concerns.
Yeah, that’s the way I would do it if you can’t get a PTR record set, just send outgoing mail via a relay. You can even limit it based on who the email is going to, for example if sending to an outlook address, use X relay, etc.
Yep. Just use SendGrid or SES or something
Finnaly i simply moved the machine to the DC was easier for my use c: Thanks for all the advices and all the help ! A lot of good ideas c: !
@ruben yush salt was used on this machine.
But we can assure 100% uptime on it because we have multiple UPS’s in this appartement and their is a few advantages with this mainly the connection speed c: but we are planning to move all our machines to a DC soon (all the ones in zurich)
