send mail migration: Newbie
 

Hi,

We have a sendmail gateway supported by Solaris 10 server. How to go about if we would like to migrate the sendmail gateway to another Solaris 10 server?

Thanks in advance.

Not sure what you are asking. If you want sendmail on a new server, just install it and copy the configuration from the old server.

How are the configuration files have to copy. After copied over, is it required to compile?

They are often (but I don't know about Solaris) kept in /etc/mail. They shouldn't need any changes assuming the configuration is to be the same.

The most important file here would be the /etc/mail/sendmail.mc file. If you copy this over the then build it. sudo bash -c /etc/mail/make to create the sendmail.cf file.
Of course this presumes that everything is staying the same. You may also have domaintable, mailertable and other extra configuration but copy those files over as well. Make sure DNS is configured correctly and port 25 is open on the server.
