==== Required information ====
- iRedMail version: 8.03
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): LDAP
- Linux/BSD distribution name and version: CentOS 6.3
- Related log if you're reporting an issue: No
====
Let me explain you in detail. I have already installed iRedMail Server with iRedAdmin and everything is working perfectly OK. This is a typical problem which I am facing ... A user is sending emails to 5 Recipient from Microsoft Outlook out of these 5 users 1 is a local user. Mistakenly the user who is sending this email does a typo error the local users email address and when he says send the message bounces back and even does not got to the other 4 outside / another domain .... this is what the client is complaining. What he says if my local recipient address is wrong but the other addresses are right so email should go to them and not to the local recipient.

How do i overcome this issue ?  Is there any way to bypass the local recipient email address and other 4 recipient should get that email without any errors. Please suggest and advise ... Thanks for your reply in advance.

Thanks & Regards,
Indranil C. Kamulkar

Re: || Email Bouncing ||

Did you check Postfix log file and make sure emails not delivered to other addresses?

Re: || Email Bouncing ||

Yes I have checked for the log and got to know that other recipients have not received that message. I have also confirmed from the recipients if they had received the message and they also confirmed with a negative reply.

Re: || Email Bouncing ||

Dear Sir,
Is there any way to disable local email recipient check so that for e.g. my domain name is abc.com and I am sending a message to neil@abc.com and this user is not listed in the local user but the message should reach other receipients
