Post Fix sends email but cannot receive...Big problem..helo

[samuelodofin]

hello guys ive just setted up ubuntu LAMP server package and i was really impressed, everything worked perfectly. I then install webmin and setted up postfix and dovecot (for IMAP and POP3)......

But am now having a problem...no emails are coming through, they all bounce back (even when i tested sending to root@XXX.XXX.XXX.XXX (thats my ip) .... it didnt come, but i was able to send mails through webmin and i received it without any problem i am also able to send mail to user@mydomail.com (from webmin) and it went through.....so i am unsure of where the problem lies.....am also not able to access the mails using outlook...eventhough dovecot is working well.........The website opens perfectly.

I dont know what step ive missed.......heres my postfix config file:

# 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


myhostname = $mydomain

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
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

# TLS parameters
smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt
smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key
smtpd_use_tls = yes
smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache

smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain =
smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject _unauth_destination
smtpd_sasl_security_options = noanonymous

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
mydestination = $myhostname, localhost.$mydomain, $mydomain
mynetworks = 127.0.0.0/8, 192.168.1.0/24
mailbox_command =
mailbox_size_limit = 0
recipient_delimiter = +
inet_protocols = all
myorigin = /etc/mailname
broken_sasl_auth_clients = yes
smtpd_tls_auth_only = no
smtp_use_tls = yes
smtp_tls_note_starttls_offer = yes
smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem
smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes
smtpd_tls_session_cache_timeout = 3600s
tls_random_source = dev:/dev/urandom
home_mailbox = Maildir/
inet_interfaces = all

Umm....any help will be very welcomed......also also...

telnet localhost 25 from terminal give this:

Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 mydomain.com ESMTP Postfix (Ubuntu)

NOTE: ive changed instances of my domain name to mydomain.....so all mydomains are valid TLD domain names..

have you checked your mail logs, /var/log/mail.info mail.error mail.warn

also have you tried to send an email thru telnet
How to Send Email Using Telnet - wikiHow

Hi when i tried sending mail from telnet it block it....saying...


Escape character is '^]'.
220 mydomain.com ESMTP Postfix (Ubuntu)
HELO mydomain.com
250 mydomain.com
MAIL FROM: rich@Mydomain.com
250 Ok
RCPT TO:somemail@yahoo.com
554 <somemail@yahoo.com>: Relay access denied

[jledhead]

you said its sending fine, so you need to check the reverse of what you tried, unless your machine is going to be the final destination for yahoo.com

reverse the emails and report back results

[samuelodofin]

ok will try right away....brb

[samuelodofin]

HEllo i did that and it worked...it ended with:

 354 End data with <CR><LF>.<CR><LF>
some test message here <CR><LF>.<CR><LF>
.
250 Ok: queued as 977901EE4045
quit 
  

and i was able to get the email through webmin and also through squirell mail which is setted up.......


ummm.....dunno wat the problem is...

[samuelodofin]

so if i send from anywhere (yahoo.com or hotmail.com) it still dosent come...... could firewall have anything to do with this?....

[samuelodofin]

Hi thanks, i figured out the problem...my ports 143 and 953 were blocked
