Followed this tutorial: http://www.howtoforge.com/virtual-users-and-domains-postfix-courier-mysql-centos5.1, and everything is working fine on my local network. What I want to achieve: allow 1 external ip (at work) to send email to anywhere (recieving mails is no prob) with windows mail, i googled allot, but i can't figure it out, i think postfix is not allowing to do what i want I quite a noob with linux telnet 192.168.0.198 25 -> working, so i can locally telnet to server (response: 220 server.bla.nl ESMTP Postfix) telnet 12.34.45.67 25 -> NOT working, can't telnet from outside (external) sending email, local network - working sending email, external - not working (email client, server requires login activated) No errors in mail.log Sep 11 21:46:39 server pop3d: Connection, ip=[x.x.x.x] Sep 11 21:46:39 server pop3d: LOGIN, [email protected], ip=[x.x.x.x], port=[55749] Sep 11 21:46:39 server pop3d: LOGOUT, [email protected], ip=[x.x.x.x], port=[55749], top=0, retr=0, rcvd=12, sent=39, time=0 main.cf: readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES myhostname = server.bla.nl mynetworks = 127.0.0.0/8 192.168.0.0/24 12.34.56.79 # #12.34.56.79 ip at work # virtual_alias_domains = virtual_alias_maps = proxy:mysql:/etc/postfix/mysql-virtual_forwardings.cf, mysql:/etc/postfix/mysql-virtual_email2email.cf virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql-virtual_domains.cf virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailboxes.cf virtual_mailbox_base = /home/vmail virtual_uid_maps = static:5000 virtual_gid_maps = static:5000 smtpd_sasl_auth_enable = yes broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination smtpd_use_tls = yes smtpd_tls_cert_file = /etc/postfix/smtpd.cert smtpd_tls_key_file = /etc/postfix/smtpd.key transport_maps = proxy:mysql:/etc/postfix/mysql-virtual_transports.cf virtual_create_maildirsize = yes virtual_maildir_extended = yes virtual_mailbox_limit_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailbox_limit_maps.cf virtual_mailbox_limit_override = yes virtual_maildir_limit_message = "The user you are trying to reach is over quota." virtual_overquota_bounce = yes proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domains $relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $recipient_canonical_maps $relocated_maps $transport_maps $mynetworks $virtual_mailbox_limit_maps content_filter = amavis:[127.0.0.1]:10024 receive_override_options = no_address_mappings
I already did, the external ip (example) of work: 12.34.56.79 mynetworks = 127.0.0.0/8 192.168.0.0/24 12.34.56.79 so the external ip where i want to send email from is already in mynetworks from outside / external i can't telnet on port 25, from the local network telnet port 25 is working, something is blocking acces, for sure it is not firewall or router configured postfix to listen also on port 2525, no response also
changed: mynetworks = 127.0.0.0/8 192.168.0.0/24 12.34.56.79 to: mynetworks = 127.0.0.0/8 192.168.0.0/24 12.34.56.79/32 doesn't change anything, the help is very appreciated
My provider blockes port 25 when you have a dynamic ip, I have a static ip and port 25 is should be open, tested it with different websites, all "test" sites say port 25 is open, can't figure out what is going on, locally everything works well. Feel free to test: server.humaheftruck.nl ip: 88.159.160.114 followed a tutorial to change to port smtp 2525, and again, locally everything is fine, from external can't get in.
I'm able to connect: Code: mh1:~# telnet server.humaheftruck.nl 25 Trying 88.159.160.114... Connected to server.humaheftruck.nl. Escape character is '^]'. 220 server.humaheftruck.nl ESMTP Postfix ehlo localhost 250-server.humaheftruck.nl 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-AUTH PLAIN LOGIN 250-AUTH=PLAIN LOGIN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN quit 221 2.0.0 Bye Connection closed by foreign host. mh1:~#
hmm, still not working from work, maybe provider work is blocking port 25, will try to figure that out Thanks for the help so far.
Spend a few hours figuring it out, isp of work blocks ALL trafic over port 25. Trying to setup postfix so it works on port 25 AND 587, no luck yet
In my router linked port 587 to 25 and that solved it wish i knew litlle bit more of linux, can't figure out why i can't get postfix to listen on port 25 AND 587
