How to change mail interface IP address

*********Exim*************
Step 1 : Shutdown the exim service.

# service exim stop or /etc/init.d/exim stop

Step 2 : Edit your exim configuration file.

# vi /etc/exim.conf

Step 3: go to "remote_smtp" section under "TRANSPORTS CONFIGURATION".

By default it would look like below:

Quote:
remote_smtp:
driver = smtp
interface = ${if exists {/etc/mailips}{${lookup{$sender_address_domain}lsearch{/etc/mailips}{$value}{}}}{}}
helo_data = ${if exists {/etc/mailhelo}{${lookup{$sender_address_domain}lsearch{/etc/mailhelo}{$value}{$primary_hostname}}}{$primary_ho stname}}

Step 4 : Remove or comment line containing "interface" and "helo_data" and add new "interface" to match with that of your new IP address. It should look like as follows:

Quote:
remote_smtp:
driver = smtp
interface = 12.12.12.12 # Your IP address.

Step 5 : Save your changes and exit out from your exim configuration file.

Note : Dont forget to set read only attributes on exim configuration file, so that it wont get reset to default automatically.

You can do it using following command:

# chattr +aui /etc/exim.conf

Step 6 : start exim service on your server.

# service exim restart or /etc/init.d/exim restart

*********SendMail***********

1) change the line below in sendmail.cf

#O ClientPortOptions=Family=inet, Address=x.x.x.x
to
O ClientPortOptions=Family=inet, Address=<ip address you want>

3) restart sendmail

SVN: File remains in conflict

This error occurs when you didn't update the SVN and try to commit changes or, someone has made changes to this file that are conflicting with your changes. There are two ways to handle this situation. Either, you can revert back the changes you want to commit and then, update the SVN and after that make the changes again and commit. The other way is, you need to resolve the conflicted files one by one. You can keep all the conflicted files in a folder and resolved it at once. >> Revert the changes steps: svn revert . -R svn up >> Resolve the conflicted files: svn resolved <file_name>
