yep, but sendmail is not the more evident to do that ;-) i'm sorry but i'm a postfix addict not a sendmail user anyway i think you can find more information on google :-)
not a all, you just configure correctly your main.cf :-) I know how to do that on postfix, like i said but not with sendmail but how i said before, you can find a lot of easy tutorial on google :-D
# See /usr/share/postfix/main.cf.dist for a commented, more complete version
# Debian specific: Specifying a file name will cause the first # line of that file to be used as the name. The Debian default # is /etc/mailname. #myorigin = /etc/mailname
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) biff = no
# appending .domain is the MUA's job. append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h
I don't know how you have configured your server ;-) and if your stmp accept relaying or need identification or is on another port... you can find a lot of really easy tutorial on the net to do that
i've forgot something, you are not on a standard port, try this :
Could I not just use postfix to send out emails rather than smtp?
# See /usr/share/postfix/main.cf.dist for a commented, more complete version
# Debian specific: Specifying a file name will cause the first # line of that file to be used as the name. The Debian default # is /etc/mailname. #myorigin = /etc/mailname
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) biff = no
# appending .domain is the MUA's job. append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h
in fact postfix is only a MTA if you only want to send email and not received them you can only use it but into airtime configuration don't fill "Configure Mail Server" but click only on the checkbox to "Enable System Emails (Password Reset)"
