Hello! I'm having a weird problem with email for one specific account on my server.
This account has several mail aliases, all of which forwards to the same Gmail address. I have this same setup for about a dozen other domains on my server, and it works perfectly for all of them except this one - which coincidentally is also the only .co.uk domain on my server - but, this worked perfectly for this domain also on my old VirtualMin server (moved to a newer one with more disk space recently). So that makes me think it's not the domain, since it worked before.
When you send an email to one of the aliases, you get the following email after a few hours:
This is an automatically generated Delivery Status Notification

So those errors would make you think mail isn't arriving. BUT, about 80% of those emails do actually arrive, usually within minutes of sending just as you'd expect! So it's really confusing to any mail senders, and I'd really like to fix this.
I've tried to trouble shoot this, but didn't really get anywhere. Any ideas for what might be wrong? Thanks in advance!
I couldn't find anything out of the ordinary in maillog, but here is a quick check of it anyway, grepped for the domain name I'm having trouble with:
Howdy,
It looks like you may be seeing some issues with your nameservers... if you go to intodns.com, have it run a DNS report on your domain there. When I did that, a few errors shows up that you may want to review.
