Mail Queue Building: 451-4.4.0 and 554-host.domain.com errors
I have a lot of servers delaying my outbound messages:
554 "host.domain.com" attempted failover to alternate host, bit that did not succeed...
554 Unfortunately your access to this mail system has been rejeted due to the sending MTA's poor IP reputation
This is starting to cause some major email issues and I need to know how to troubleshoot and resolve.
I'm not blacklisted, at least not yet

Please check your Reputation on www.senderbase.org and see if it is poor. If it is, it will improve over time, but not in the next few days.

It is, I've checked there already.
Any way to speed up the process? This is killing business.

Configure your SEND Connector to use a SMARTHOST (your ISP's Mail server) for now instead of direct via DNS and your mail should flow a bit better (it may not be perfect as it depends on your ISP and their reputation / blacklistings).

My ISP is a fiber company, no mail servers.
That's not very helpful of them.
Then unless you can find / pay for a Smarthost in the mean-time, you are a little bit snookered.

ok, so what would cause a bad reputation?
If you are a new server using an IP address that hasn't sent mail before and thus there is no history of your being a good / bad / indifferent mail server.
Once you have established a pattern of good (not being reported for spam) behaviour, you should be fine. Sadly - that is just a waiting game and usually is in the weeks not days time frame.

We've been around for years. Using this IP for 2 years.
I added another server but everything sends out via old sever via normal IP address
This doesn't make any sense

Can you divulge your IP / domain name, either here or in an email to alan @ it-eye.co.uk. If you divulge it here, I can hide it for you.

I can send the headers of an email I sent to my personal address if it would help.

ok, should it be my public dns name pscweb.domain.com or my internal server.domain.com?
Your Public name.

Perfect, this has already brought us up to neutral!
