Hi Railway Team,

I need to add the following DNS records to mirkaso.com

I couldn't do it on my own.

(Railway-purchased) for email service setup:

MX @ mx1.improvmx.com 10

MX @ mx2.improvmx.com 20

TXT @ v=spf1 include:spf.improvmx.com include:send.resend.com ~all

TXT _dmarc v=DMARC1; p=none; rua=mailto:dmarc@mirkaso.com

CNAME resend._domainkey dkim1.resend.io

CNAME resend2._domainkey dkim2.resend.io

No nameserver changes needed — just adding records to existing zone.

Thanks!

You should be able to manage your DNS records at https://railway.com/workspace/domains.

Sure, I've tried doing this several times, but I keep getting a pop-up notification saying "Failed to save DNS record

Problem processing request."

I also have a video recording, if that helps...

That error usually means one record is failing validation, not that every DNS record is wrong.

I’d add them one by one instead of saving the whole batch. Start with MX records, then SPF TXT, then DMARC TXT, then the two DKIM CNAMEs. That tells you exactly which record Railway is rejecting.

Also for SPF, keep only one TXT at @ that includes both providers. Multiple SPF TXT records can break email validation, so your combined value is the right idea:

v=spf1 include:spf.improvmx.com include:send.resend.com ~all

If one specific record keeps throwing Problem processing request, send Railway that exact name/type/value plus the video.

I deleted the old MX record and was able to add a new one. I'm not sure if that's related. Thanks for your reply.
