How to configure Sendmail for simply use?

Hi lads,

would you be able to advice, please, how to configure Sendmail for sending casual emails (like with Thunderbird or Outlook). Before I used Exim 4 in Debian and did not have any problem with configuration.
Knowledges almost zero, but know what is MTA, MUA, etc. Workstation is typical, OS SEDE.

Thank you in advance.

As I understand, should be somewhere a place to put SMTP address of ISP.
