hi guys,

today morning i was not getting any emails and i got very frantic and scared.
So tried to look up the logs and couldnt see anything wrong.
Disabled avasmid, jail2ban, etc just to pinpoint the problem.
Updated the server and then rebooted and yet could not get any emails

Later realized that I was missing mx records on my domain dns and thought that was the cause.
I recently added more subdomains and I think that might have caused a clash.

Could MX record be a cause for undelivered emails? (I am right now waiting for the MX record to propergate)
Feeling stressed out but hope this addresses it.

Please advise.

Thanks
Kevin
