No, the SMTP mail section is ONLY for if you don't want (or can't) use the built in PHP mail() function. If mail() works fine for you then you don't need to enter any SMTP information.
i am about to present your forum within my company as a possible solution. However when i installed it on our webserver and turned on the user account activation i encountered a problem : after a user enters his/her data and hits on submit a page shows up stating a mail had been sent to the user ... so far so good ... but these mails never show up.
Ive successfully used the mail() function on this server(IIS) but phpbb seems to have problems here.
Any idea if there is a lil bug involved here ? Since im not fond of reconfiguring a server that cost already over 500k to install an unessesary SMTP Service id apreciate help here.
Finally a thumbs up to the team - doing good work there !
