Hi there, My email workst just the half way as it should ;-) I didi anything wrong or forget something but I couldn't find it by myself. I can connect to the mailserver with outlook and thunderbird etc.. even the webinterface (roudcube and squirrelMail works fine. recieving mails works correctly, but sending mails doesen't work.... in outlook express it says ... mail server not found ... in thunderbird the same .. that sounds as if I forgot something .... ;-/ but what ? here my postfix main.cf: Code: # See /usr/share/postfix/main.cf.dist for a commented, more complete version 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 myhostname = server1.pc1service.gotdns.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname #mydestination = server1.pc1service.gotdns.com, localhost.pc1service.gotdns.com, localhost relayhost = mynetworks = 127.0.0.0/8 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all mailbox_command = smtpd_sasl_local_domain = smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination smtpd_tls_auth_only = no smtp_use_tls = yes smtpd_use_tls = yes smtp_tls_note_starttls_offer = yes smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt 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/ virtual_maps = hash:/etc/postfix/virtusertable mydestination = /etc/postfix/local-host-names I'm using POP... thanks for helping ;-) best regards Leander
Do you use an FQDN or an IP address in your email client as SMTP/POP server? If you use an FQDN, I guess it's a DNS problem. What's the output of Code: netstat -tap and Code: iptables -L ?
Hi, ok, Code: root@server1:~# netstat -tap Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 *:mysql *:* LISTEN 2230/mysqld tcp 0 0 *:81 *:* LISTEN 2446/ispconfig_http tcp 0 0 *:ftp *:* LISTEN 1371/proftpd: (acce tcp 0 0 server1.pc1servi:domain *:* LISTEN 2674/named tcp 0 0 localhost.locald:domain *:* LISTEN 2674/named tcp 0 0 *:smtp *:* LISTEN 1455/master tcp 0 0 localhost.localdoma:953 *:* LISTEN 2674/named tcp6 0 0 *:imaps *:* LISTEN 2134/couriertcpd tcp6 0 0 *:pop3s *:* LISTEN 2173/couriertcpd tcp6 0 0 *:pop3 *:* LISTEN 2151/couriertcpd tcp6 0 0 *:imap2 *:* LISTEN 2107/couriertcpd tcp6 0 0 *:www *:* LISTEN 2482/apache2 tcp6 0 0 *:ssh *:* LISTEN 2370/sshd tcp6 0 0 ip6-localhost:953 *:* LISTEN 2674/named tcp6 0 0 *:https *:* LISTEN 2482/apache2 tcp6 0 0 server1.pc1service.:ssh ::ffff:192.168.1.:57121 ESTABLISHED2371/0 root@server1:~# and: Code: root@server1:~# iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination root@server1:~# I have a dynamic IP - so I use DynDNS...what do I have to change?

This looks fine so far. Is your workstation inside your private network? What did you use as SMTP server in outlook? Your dyndns domain or your internal IP address?
The Server is inside a Privat Network (192.168.1.101) The Ports are successfully forwarded. Code: WAN TCP 25 (SMTP) 192.168.1.101 25 (SMTP) SMTP-Server1 WAN TCP 110 (POP3) 192.168.1.101 110 (POP3) POP3-Server1 WAN TCP 143 (IMAP) 192.168.1.101 143 (IMAP) IMAP-Server1 WAN TCP 993 192.168.1.101 993 IMAPs-Server1 WAN TCP 995 192.168.1.101 995 POP3s-Server1 my Outlook entries: POP-Server: pc1service.gotdns.com and as SMTP-Server the same. POP works, SMTP not ;-/ for what is the optipn Backup MX in DynDNS.org? Is it necessarry to tick this option? Code: Your modifications have been completed. Details of the new settings are below. Hostname: pc1service.gotdns.com IP Address: 84.164.159.69 Wildcard: Y Mail Exchanger: none Backup MX: N Code: root@server1:~# hostname server1.pc1service.gotdns.com root@server1:~# hostname -f server1.pc1service.gotdns.com
You don't need the Backup MX. Is your client PC in the same network than your mail server? If so, please try your mail server's internal IP address in your email client. I guess your ISP is blocking port 25. I'd contact them and ask.
Hi Till, you guessed right ;-) - now it's able to communicate with the server. But if I try to send an email it says that the mail is to big to send but there is only the word test in it no attachments and stuff like that. The mailbox should be big enough - so what's the matter? and how to fix that the server is able to communticate without beeing in the localnetwork? Thank you and Falko very much ;-) Leo [edit] SquirrelMail suddenly shows me this error when I'm trying to send an email via the webinterface .. ?! Requested action not taken: insufficient system storage Server replied: 452 Insufficient system storage [edit again] ^^ I think my harddrive is full - only 13MB left ... have to check (& renew) this out first ... Leo
Ok I did. So now it's working if I enter the IP adress instead of the domain. but only in the local network ant not from outside ;-) any idea? ports in the router are forwarded and tested with nmap ... :-? thx! Leander
I don't really know what I did wrong - but I reinstalled _everything_ the OS and ISP and now it seems to work except ..... http://howtoforge.com/forums/showthread.php?t=8438 Thank You ;-) Leander
