Question how sendmail works
Excuse me for this question really for dummies!
I would like to know how sendmail works, obviously even in few words.
If it uses a mail server or relay to send mail, if there is some check that sendmail makes to the from address and so on...
Thank you very much.

Please search the forums first.

https://www.unix.com/solaris/12470-sendmail-config-help.html?s=

See the "How do I send email?" faq as well...

Your best bet for all-around knowledge is probably to go to www.amazon.com and puchase a sendmail book.

There's also an faq for that.

i would strongy agree with RTMs opinion.

Sendmail is a huge beast and to tackle what it is and how it works i think is beyond this forum.

the syntax for the config file is complcated and pretty awkward if you dont have the book on hand as a referance (unless you deal with sendmail on a daily basis)

but yes sendmail is a mail server, and yes sendmail can forward its mail to a relay server or it can act as a relay server.
