Regular outgoing mail and small email list email blasts being rejected...

[Gman]

A number of our customers are starting to get increased undeliverable messages and tons of returns if they send out an email blast (from Dada mail running in cgi-bin, op out program with small lists in it). We've gone to great lengths at times to double check and some returned mail messages are actually coming back from accounts that are active even though error message will say something like 'unknown user', etc. We have other servers not with HostNine that run Dada mail and a 1-2% undeliverable rate is unusual and high. But for accounts we've migrated to HostNine it seems a 50%+ at times, of emails sent out in an email blast, are coming back undeliverable with various error messages. A couple of them are below. Again, the error message don't always check out. Like 'Unknown user' but we know the user is there or 'No such recipient', etc. when we know it's an accurate address.

Somtimes the error says it's a spam issue or a 'reputation' issue. Although I don't see the HostNine servers we use on Blacklists could it be

1) A 'reputation' issues due to a lot of spamming or something coming off the servers?
2) Could it be that HostNine SMTP servers are setup some way as to not allow email to to be sent out to remote destinations
3) Or some stuff being put in the headers of outgoing email from HostNine servers being flagged and rejected?

We've opened up a ticket and so far only get 'It looks like most of these email accounts don't exist'. There's got to be something else going on.

Any thoughts on what might be going on would be great.

Below are a couple examples of error messages.

Thanks a bunch for any input!!!

This message

Recipient address rejected: User unknown in relay recipient table

looks like a QMAIL server reply to an attempt to relay through it.

I am starting a new marketing company which runs from one of my domains (I’m a reseller).
I will be sending bulk e-mail, in order to reach potential customers inside our lists.
(The lists have been gathered through the work on our sites)

In the first moment that I contracted H9 services, I have a trouble regarding spam, it was caused by robots that took control of my site.

Now a like to know which e-mail power I can use without being considered as spam.

Can I have a greater email capacity because I am reseller?

For email marketing, one should really use a service like MailChimp
