Unhappy Postfix timeout after data error

I recently installed postfix on my system.

here is the output of postconf -n

alias_database = hash:/etc/mail/aliases
alias_maps = hash:/etc/mail/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/lib/postfix
default_destination_concurrency_limit = 2
home_mailbox = .maildir/
inet_interfaces = $myhostname,, localhost
mailq_path = /usr/bin/mailq
manpage_directory = /usr/share/man
mydestination = $myhostname, localhost.$mydomain, $mydomain,
mynetworks =, x.x.x.x
myorigin = somedomain
newaliases_path = /usr/bin/newaliases
readme_directory = /usr/share/doc/postfix-2.0.16-r1/readme
sample_directory = /usr/share/doc/postfix-2.0.16-r1/sample
sendmail_path = /usr/sbin/sendmail
setgid_group = postdrop
smtpd_client_restrictions = check_client_access hash:/etc/postfix/client_access
smtpd_error_sleep_time = 10s
smtpd_hard_error_limit = 50
smtpd_soft_error_limit = 5025
unknown_local_recipient_reject_code = 450

when people from x.x.x.x try to send mail to or relay through the server
this is what i see in the logs (with debugging on)

Nov 13 08:58:41 [postfix/smtpd] > unknown[x.x.x.x]: 421 Error: timeout exceeded
Nov 13 08:58:42 [postfix/smtpd] vstream_fflush_some: fd 11 flush 29
Nov 13 08:58:42 [postfix/smtpd] timeout after DATA from unknown[x.x.x.x]
Nov 13 08:58:42 [postfix/smtpd] vstream_fflush_some: fd 11 flush 0
Nov 13 08:58:42 [postfix/smtpd] vstream_fflush_some: fd 14 flush 0
Nov 13 08:58:42 [postfix/smtpd] disconnect from unknown[x.x.x.x]

They are behind a dlink di-604 with the latest firmware... Using Outlook 2003 as the email client...(i know, not my choice)

Any ideas?

well i don't know if you are on broadband, however the smtp_data_done_timeout option, which defaults to 600 seconds can be increased; are you sure you are not having network related problems?

there are 2 people at this location, they are both on xp with office 2003. When another person visited the location with a windows me laptop and office 97, they were able to send perfectly.

I don't think that the problem is office 2003, because other people use that at another location with no problems.
