I have got to setup a mail server(ubuntu cloud server) and I'm preparing for it on my home computer(ubuntu vm) to make sure my manager that it works and I could. I started with Postfix, Dovecot, and Squirrelmail following the tutorial and if it works here then I can start doing it on the cloud server. The home computer has dynamic public ip address(the ip changes only if I restart the router) and I have registered a trial domain for this public ip(A-
maillts.mooo.com) which could be globally resolved.
I'm having problem in sending & receiving mails from and to the server. I could not send mails to gmail accounts but I was able to send mails to yahoo for 2,3 times and after that I could not(here the log shows below).
The below are my mail server configurations,
myhostname = lts.mooo.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = mooo.com, lucid, localhost.localdomain, localhost relayhost = mynetworks = 192.168.1.4 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all inet_protocols = all smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth-client smtpd_sasl_local_domain = mooo.com smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_sasl_auth_enable = yes smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination #inet_interfaces = all smtpd_tls_auth_only = no smtp_tls_security_level = may smtpd_tls_security_level = may smtpd_tls_CAfile = /etc/ssl/certs/cacert.pem smtp_tls_note_starttls_offer = yes smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_session_cache_timeout = 3600s tls_random_source = dev:/dev/urandom home_mailbox = Maildir/ smtpd_sasl_authenticated_header = no smtpd_sender_restrictions = mailbox_command = smtp_use_tls = no smtpd_tls_mandatory_protocols = SSLv3, TLSv1 smtpd_tls_mandatory_ciphers = medium
Dovecote: Just made changes as per the tutorial.

I haven't received any of the mails sent from external domains(yahoo, google to email@example.com) yet(I know the dynamic public ips are not choosen but want to check if it works). I need some help here so that I can receive mails from any domain and send to any domain.
I hope some are running their own mail servers and could help me here finding out where I'm doing wrong, giving some clues and informations to reach my goal.
