Description

I need someone to fix a couple of bugs in our mailserver configuration. I believe we are currently using Dovecot and exim.

Mail whose 'Envelope-from' is a domain configured on our server should be accepted only if the user has authenticated. The same check should (I think) be applied before generating error messages to the alleged sender's mailbox.

At present, spammers seem able to send messages from user1@ourdomain to user2@ourdomain without any authentication. If user2 doesn't exist, user1 gets a bounce message. If neither user exists, the bounce lands in my catchall maildir.

OPTIONAL: If possible, I'd like to set it up such that an authenticated SMTP user can send messages only from their own address(es). If you can do this, please let me know, as I'd be willing to pay more for this functionality. This should be able to work out which users would be able to read a message sent to the alleged sender's address. (please ask if this isn't clear, I could probably explain more clearly in a dialogue)

Here's a copy of the current config files.

(They were based on ones from another system. I think all references to cleo are commented out now)

I can switch your mail server to qmail, you will be more happy than using exim. exim is slow and will eat your CPU :-)

It seems your mailserver is compromised with spammer/hacker. So It'd be better to use more advanced and powerful authentication based emailing server. If you want I could setup a qmail server for you. Another thing if you want fix existing problem in your email server contact me on freelancer.com. Thanks, Amit Rana

Veteran UNIX system administrator with 10+ years experience. Many of my current clients are UNIX based internet service providers and web hosting company's. Price is inclusive of all services you will need with 24/7 phone support. I also provide my own hosting infrastructure if you wish to migrate and cut monthly costs down. Considering what you have placed in project proposal it appears as if your server has been compromised. If that is the case the only remedy is a server rebuild or switch to a different server setup. Price is estimated based on the assumption it is simply a configuration issue and not a compromise. Thank you for your consideration and I look forward to working with you.
