Hi all!

For some reasons after I've setup sendmail server, I can send to everyone from outside or local but people from the outside can't send email through my email address. I'm wonderring if my ISP blocks the incoming port (pop3). When I checked on maillog status, it confirms that is send but I don't get any incoming emails.

You must configure the MTA to recieve mail

1. modify /etc/mail/sendmail.mc
locate the line
Comment out the line by prepending it with "dnl ", like so:
2. Build a new sendmail.cf in the same directory by:
# m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf

3. restart sendmail with:
# service sendmail restart

I don't see that line DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1,Name=MTA')
in my sendmail.mc

Here's what I have:


include(`../m4/cf.m4')
VERSIONID(`default setup for Slackware Linux')dnl
OSTYPE(`linux')dnl

dnl# These settings help protect against people verifying email addresses
dnl# at your site in order to send you email that you probably don't want:
define(`confPRIVACY_FLAGS', `authwarnings,novrfy,noexpn,restrictqrun')dnl

dnl# Uncomment the line below to send outgoing mail through an external server:
dnl define(`SMART_HOST',`mail.mydomain.com')
dnl# No timeout for ident:
define(`confTO_IDENT', `0')dnl

dnl# Enable the line below to use smrsh to restrict what sendmail can run:
dnl FEATURE(`smrsh',`/usr/sbin/smrsh')dnl

dnl# See the README in /usr/share/sendmail/cf for a ton of information on
dnl# how these options work:
FEATURE(`use_cw_file')dnl
FEATURE(`use_ct_file')dnl
FEATURE(`mailertable',`hash -o /etc/mail/mailertable.db')dnl
FEATURE(`virtusertable',`hash -o /etc/mail/virtusertable.db')dnl
FEATURE(`access_db', `hash -T<TMPF> /etc/mail/access')dnl
FEATURE(`blacklist_recipients')dnl
FEATURE(`local_procmail',`',`procmail -t -Y -a $h -d $u')dnl
FEATURE(`always_add_domain')dnl
FEATURE(`redirect')dnl
dnl# Turn this feature on if you don't always have DNS, or enjoy junk mail:
dnl FEATURE(`accept_unresolvable_domains')dnl
EXPOSED_USER(`root')dnl
dnl# Also accept mail for localhost.localdomain:
LOCAL_DOMAIN(`localhost.localdomain')dnl
MAILER(local)dnl
MAILER(smtp)dnl
MAILER(procmail)dnl

does anyone have any ideas how to make users from outside SENDING email to you??
It's driving me nuts!!

ps : I'm using dynamic DNS.
