Email Rejection

[nervous]

The core of my business is with schools, and we've suddenly started getting a lot of mail rejections from teachers- even teachers who I've been mailing up until last week.

The system that they nearly all use is esinet, and all the rejections are from is of the [e-mail] format

When I get a bounce back, I get this every-time (from any school using the system):

----- Transcript of session follows -----
... while talking to in.mx.ifl.net.:
<<< 554-in3.mx.ifl.net
<<< 554 Your access to this mail system has been rejected due to the sending MTA's poor reputation. If you believe that this failure is in error, please contact the intended recipient via alternate means.
554 5.0.0 Service unavailable

What does this mean and what can I do about it? I've changed nothing whatsoever, so I'm at a loss to understand why my MTA suddenly has a poor reputation (whatever an MTA is).

I'd appreciate any help you can provide folks, I need to fix this and fast.

Thanks in advance,
N.

MTA : Message Transfer Agent
sort of like a relay server, sounds as though one of them in the chain is blacklisted and will not pass on emails

speak to your ISP about using another MTA, or unblacklisting it

All my computer stuff is done through Register 1- is that who I need to talk to? Or do you mean the people that physically charge me for the internet (vodafone)? Sorry, I'm no good with this sort of thing. God, I'm hoping I don't have to deal with Vodafone. Please don't let it be Vodafone.

Also, any idea why I'd suddenly be blocked?

How do you send email? By which I mean, what is the SMTP server configured to in your MUA (that's "Mail User Agent", e.g. Outlook or Thunderbird or PINE).

it's a POP3 and it's mail.mycompanyname.com

is that the right info? do you want more? again, most of these folks we've been dealing with for years with no issues.

God, please not Vodafone. Please.

Sounds to me like the schools subscribe to a blacklist and your ISP has been blacklisted. It is quite possible that another customer at your ISP has been spamming and therefore mail from your ISP is seen as unwanted.

You need to speak to your ISP and get them to talk to the blacklist maintainer.

POP3 is the recieving mechanism. SMTP is for sending. As others have said - talk to register1.

The problem is that the company providing the email service to your clients has taken a dislike to the server you are sending ("relaying" is the term normally used) through. This might be the one operated by Vodafone or it might be Register1 (Register1 seem to offer a mail relay service on all their hosting products). In either case register1 should be able to help - if their server has the problem they can try to do something about it, if you're sending through vodafone and it's vodafone with the problem then r1 can tell you how to send through them instead.

Ok, thanks, I greatly appreciate it.
