Turning Off Execution Of "Mail Delivery Failed: Returning Message To Sender" In Exim

Jun 24, 2009

My mail server receives tons of messages directed towards bogus, non-existant addresses at my domain. When those addresses don't exist, it creates a reply email with the subject "Mail delivery failed: returning message to sender". How do I stop exim from doing this?

Hundreds Of Messages In Mail Queue

Mar 10, 2007

I have hundreds and hundreds of messages in mail queue waiting delivering. Log file says:

connect to remote.host[000.000.000.000]: server refused to talk to me: 421 4.7.0 remote.host Error: too many connections from my-servers-ip

delivery temporarily suspended: connect to remote.host[000.000.000.000]: Connection timed out

(I replaced real IP addresses with 000, my-servers-ip and hostname with "remote host")

It happends only with one host (the most popular free email provider in my country). All emails to yahoo, gmail etc are being delivered without any problems.

What does it mean - too many connections from my server? I have a busy dating website and php script sends out a lot of email notifications (for example - when users get new instant messages). Anyway, I never heard that email providers limit the number of emails from the same server. During the night time all messages from mail queue are being delivered, but at day time this number sometimes grows to 1000.

I have Postfix installed.

I have a problem with hotmail that outgoing message not reached by hotmail only . all other mail is ok and spf recoed is pass . DomainKey-Status: good (test mode)

i take new server from theplanet and i see the same problem!

all microsoft hotmail support responde is same :
We have identified that messages from your IP xx.xx.xx.xx are being filtered based on the recommendations of the SmartScreen filter. SmartScreen is the spam filtering technology developed and operated by Microsoft. SmartScreen is built around the technology of machine learning. SmartScreen's filters are trained to recognize what is spam and what isn't spam. In short, we filter incoming emails that look like spam. I am not able to go into any specific details about what these filters specifically entail, as this would render them useless.

i make what all on postmaster.live.com but no way
msg's are sent from ssh . webmail , outlook express and nobody all same

and if there datacenter can Availability a server sending to hotmail without problem add offers

We are a company for hosting and most of our customer's are confuse of that problem
