I've set up a new email server and have placed one of my domains (texasgeotech.com) on. My customer is claiming that there are emails they are not receiving -- however I scour the logs - maillog, dovecot.log, iredapd.log .. and I'm not seeing anything (out of ordinary) being rejected, denied .. etc. They do receive emails, and they can send emails. There have been a few hiccups of some server blacklisting the other, but we there was an 'epaper' trail (bounce back / rejection notices ..) and we were able to get those resolved.
There is one domain - pocca.com, that I receive absolutely no indication on. My customer's wife works at the organization -- and she sends an email, however my server never receives it. I'm using splunk to parse the three logs -- and I see several emails going to pocca.com -- but nothing is ever received. (I'm currently talking to their admins to determine why emails are not being sent to us .. it seems like it's 100% on their end -- but before the server migration it was working.)
If one domain / server is falling into a blackhole, then it's not unreasonable that other domains / servers are affected. It's been a week since I've implemented the new sever and transferred their email to it -- so DNS should have propagated by now.
So is there something wrong with my server?
