Hello, I hope somebody out there can help me with my problem concerning postfix. I discovered yesterday that the connection between our postfix server which is a relay host with an acl and our exchange server seems to be temporarily broken or is unavailable. There is the message in the logs: connection timed out (port 25) It seems to me that the mails are being sent after a postfix restart. Here are the common outputs/configs. If more is needed, just ask for it. Regards ____ mail.info Code: Jan 10 10:58:14 g99la004 postfix/smtp[29828]: connect to g099sx04.ourdomain[our ip]: Connection timed out (port 25) /var/log/mail: Code: Jan 11 09:00:58 g99la004 postfix/smtpd[595]: 079A9179DA: client=servername[server-ip] Jan 11 09:00:58 g99la004 postfix/cleanup[600]: 079A9179DA: message-id=<[email protected]> Jan 11 09:00:58 g99la004 postfix/qmgr[365]: 079A9179DA: from=<[email protected]>, size=8963, nrcpt=1 (queue active) Jan 11 09:01:28 g99la004 postfix/smtp[603]: 079A9179DA: to=<[email protected]>, relay=none, delay=30, status=deferred (connect to g099sx04.ourdomain[serverip]: Connection timed out) If I restart postfix then it seems to me that the mails are being sended: mail.info after postfix restat: Code: Jan 11 09:16:34 g99la004 postfix/qmgr[843]: 079A9179DA: from=<[email protected]>, size=8963, nrcpt=1 (queue active) Jan 11 09:16:35 g99la004 postfix/smtp[854]: 079A9179DA: to=<[email protected]>, relay=g099sx04.ourdomain[server-ip], delay=937, status=sent (250 2.6.0 <[email protected]> Queued mail for delivery) Jan 11 09:16:35 g99la004 postfix/qmgr[843]: 079A9179DA: removed output of postconf -n: Code: alias_maps = hash:/etc/aliases biff = no canonical_maps = hash:/etc/postfix/canonical command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/lib/postfix debug_peer_level = 2 defer_transports = disable_dns_lookups = yes disable_mime_output_conversion = yes html_directory = /usr/share/doc/packages/postfix/html inet_interfaces = our ip ::1 inet_protocols = all mail_owner = postfix mail_spool_directory = /var/mail mailbox_command = mailbox_size_limit = 0 mailbox_transport = mailq_path = /usr/bin/mailq manpage_directory = /usr/share/man masquerade_classes = envelope_sender, header_sender, header_recipient masquerade_domains = our domains masquerade_exceptions = root message_size_limit = 10240000 mydestination = $mydomain myhostname = g99la004.ourdomain mynetworks = $config_directory/our_networks newaliases_path = /usr/bin/newaliases queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/packages/postfix/README_FILES relay_domains = $mydomain, $my_relay_domains relayhost = [g099sx04.ourdomain] relocated_maps = hash:/etc/postfix/relocated sample_directory = /usr/share/doc/packages/postfix/samples sender_canonical_maps = hash:/etc/postfix/sender_canonical sendmail_path = /usr/sbin/sendmail setgid_group = maildrop smtp_never_send_ehlo = yes smtp_sasl_auth_enable = no smtp_use_tls = no smtpd_banner = $myhostname - powered by $mail_name smtpd_client_restrictions = check_client_access hash:/etc/postfix/mail,reject smtpd_helo_required = yes smtpd_helo_restrictions = smtpd_recipient_restrictions = permit_mynetworks,reject_unauth_destination smtpd_sasl_auth_enable = no smtpd_sender_restrictions = hash:/etc/postfix/access smtpd_use_tls = no strict_8bitmime = no strict_rfc821_envelopes = no transport_maps = hash:/etc/postfix/transport unknown_local_recipient_reject_code = 550 virtual_alias_domains = hash:/etc/postfix/virtual virtual_alias_maps = hash:/etc/postfix/virtual

Yes, I have changed this value, but there is no improvement until now. The connection still gets a time out after some time.
