Have been pulling my hair out for quite a while now. I have configured a Postfix + Dovecot server. Originally when I had set it up I could receive emails but I couldn't send them. I ended up working out that I had an issue in the postfix main.cf file where I wasn't allowing [::1]/128 in mynetworks. Anyway since fixing that I can send, though I now can't receive any emails from the outside world. I did telnet on port 25 and created an email to come from an outside domain (@gmail.com) and the mailbox received it just fine. Though when I send the email from gmail it just doesn't seem to get there (though gmail receives emails I send from the mail server) I can also successfully send an email from one user on the server to another user on the server still using the roundcube webmail client (so not just through telnet). Am hoping its something stupid that I for some reason have just overlooked! Here is the postconf -n output alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases command_directory =/usr/sbin compatibility_level =2 daemon_directory =/usr/libexec/postfix data_directory =/var/lib/postfix debug_peer_level =2 debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin ddd $daemon_directory/$process_name $process_id & sleep 5 html_directory = no inet_interfaces =all inet_protocols =all mail_owner = postfix mailq_path =/usr/bin/mailq.postfix manpage_directory =/usr/share/man meta_directory =/etc/postfix mydestination = localhost mydomain = mydomainname.com myhostname = mydomainname.com mynetworks =127.0.0.0/8,xxx.xxx.xx0.0/20,[::1]/128 myorigin =$mydomain newaliases_path =/usr/bin/newaliases.postfix queue_directory =/var/spool/postfix readme_directory =/usr/share/doc/postfix/README_FILES sample_directory =/usr/share/doc/postfix/samples sendmail_path =/usr/sbin/sendmail.postfix setgid_group = postdrop shlib_directory =/usr/lib64/postfix unknown_local_recipient_reject_code =550 virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf virtual_mailbox_domains = mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf virtual_mailbox_maps = mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf virtual_transport = lmtp:unixrivate/dovecot-lmtp Here is the doveconf -n output #2.2.24(a82c823):/etc/dovecot/dovecot.conf # OS: Linux 4.2.3-300.fc23.x86_64 x86_64 Fedora release 23(Twenty Three) ext4 auth_debug = yes auth_mechanisms = plain login auth_verbose = yes debug_log_path =/var/log/dovecot-debug.log info_log_path =/var/log/dovecot-info.log log_path =/var/log/dovecot.log mail_debug = yes mail_location = maildir:/var/mail/vhosts/%d/%n mail_privileged_group = mail mbox_write_locks = fcntl namespace inbox { inbox = yes location = mailbox Drafts { special_use =\Drafts } mailbox Junk { special_use =\Junk } mailbox Sent { special_use =\Sent } mailbox "Sent Messages"{ special_use =\Sent } mailbox Trash { special_use =\Trash } prefix =} passdb { args =/etc/dovecot/dovecot-sql.conf.ext driver = sql } service auth-worker {user= vmail } service auth { unix_listener /var/spool/postfix/private/auth {group= postfix mode =0666user= postfix } unix_listener auth-userdb { mode =0600user= vmail }user= dovecot } service imap-login { inet_listener imap { port =143}} service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp {group= postfix mode =0600user= postfix }} ssl = required ssl_cert =</etc/pki/dovecot/certs/dovecot.pem ssl_cipher_list = PROFILE=SYSTEM ssl_key =</etc/pki/dovecot/private/dovecot.pem userdb { args = uid=vmail gid=vmail home=/var/mail/vhosts/%d/%n driver = static } Any idea's?
