Thread: Postfix/Dovecot -- Cannot send email from within a Client (i.e. Thunderbird, Outlook)

i made new ubuntu 11.04 lts server after ubuntu 8.10 server bit dust. recall, difficult thing set on original server smtp-authentication send emails using email client such thunderbird, outlook, or iphone. took me forever figure out. now, new server, i'm having same issue. i'm using standard installation of dovecot-postfix , set along installation of ubuntu 11.04. did setup using internet site using domain name. receive email fine, , can send email using web interface setup squirelmail site. errors occur when attempt send (i have no issue receiving) emails iphone, thunderbird, or other outside client. put in username , password always, , receive error smtp authentication fails. i've tried entering username , password both username , username .domain, neither works. i'm using same thunderbird setup older ubuntu 8.10 server (albeit updated security certificates), yet cannot passed error. questions these:

1. which software problem (dovecot or postfix)?
2. how fix smtp authentication error?

i've attached main.cf file information below:

# see /usr/share/postfix/main.cf.dist commented, more complete version


# debian specific: specifying file name cause first
# line of file used name. debian default
# /etc/mailname.
#myorigin = /etc/mailname

smtpd_banner = $myhostname esmtp $mail_name (ubuntu)
biff = no

# appending .domain mua's job.
append_dot_mydomain = no

# uncomment next line generate "delayed mail" warnings
#delay_warning_time = 4h

readme_directory = no

# tls parameters
smtpd_tls_cert_file = /etc/postfix/ssl/mail.crt
smtpd_tls_key_file = /etc/postfix/ssl/mail.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

# see /usr/share/doc/postfix/tls_readme.gz in postfix-doc package for
# information on enabling ssl in smtp client.

myhostname = gracefam.net
alias_maps = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = gracefam.net, claytonserver.gracefam.net, localhost.gracefam.net, localhost, oremrx.com, mysweetweb.com, oswaldnet.com, homemakeoveraf.com
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 192.168.0.0/24
mailbox_command = procmail -a "$extension"
mailbox_size_limit = 0
recipient_delimiter = +
smtpd_recipient_restrictions = permit_mynetworks reject_unauth_destination permit_sasl_authenticated
broken_sasl_auth_clients = yes
smtpd_sasl_auth_enable = yes
smtpd_tls_cafile = /etc/postfix/ssl/cacert.pem
