Hi guys,In my office we are running a mail server with horde. the server is running well but the sendmail server is sending unwanted mails to some unknown email address and get bounced ... [by ashrafy84]
I've been looking for a replacement mail server, I've been using a Communigate Pro server to send my mail, over time it's evolved and now not only sends my mail, but mail for several applications, it's sending about 750,000 - 1.5 Mill a week and was never setup to do this.
This is a continuation of a previous question here: Sendmail won't send email to same domain
Initially I was having trouble getting a webserver (say domain.com) running Sendmail 8.14.4 on Ubuntu 13.10 to deliver a message to an address at the same domain name (say [email protected]). The mailserver is actually managed elsewhere - mail.domain.com points to a separate IP in the DNS.
i need help for sendmail configuration in our linux machine.
Here the things:
I want to send email to outside by using our exchange server as the mail relay.But when sending the email through the server,it will response "user unknown".To make it worse, it will bounce back all the sent message to my localhost.
I already tested our configuration by using external mail server such as gmail and yaho
