Inbound email issues - hoping it is DNS propogation issues

Hi Everyone,

On Monday afternoon I came into work and found out that we had very sporadic inbound email and only from some domains. After restarting, and doing the usual troubleshooting I still came up empty handed. I started to think about it maybe being a DNS issue. I traced the problem back to our Registrar of our domain name - our domain had expired - YIKES! - I was not warned of this and I happily thought I had a few years on this still. Needless to say I renewed this asap. I also changed the DNS pointers from back to my DNS host -

This was about Monday at around 12am. I am still having issues with inbound email, while it has got better there still seems to be quite a few emails that are not getting through. Very few of these are also receiving NDR's....?

I have a couple of questions to help me be confident that I am on the right track and it is just a question of time:
1. Do you all think this is the issue. I am fairly confident but I guess I dont really understand it as the entries on my DNS host have not changed at all - surely this is what propogates not the dns pointers on the registrar?

2. Is there anything else you can think of that may be causing the problem? I have relayed the information onto our users so need to be quite certain of this.....

I have tested out our domain ( against all the dns tools on the internet and everything looks good so I am just a little worried about this - hoping you guys can relax my nerves a little....!

I have put 500 points to this question as it is urgent for me to have a concrete answer on this.

Many Thanks

    Accepted Solution

    Yes, your domain name expiration is most likely the problem. It will slowly get better as the new nameserver records from your registrar propagate. This can take 72 hours or more depending on what the ttl was set to.

    You can use the tools found on to verify whether your dns records have propagated properly.  There is also a link to on the same page. Use this to check your domain. Specially the mail related items. It should put your mind at ease.

    Are your corporate email signatures appalling?

    Is it scary how unprofessional your email signatures look? Do users create their own terrible designs and give themselves stupid job titles? You can make this a lot easier for yourself by choosing an email signature management solution from Exclaimer today.
