Hello, I can't send emails using Postfix. I would like to use the port 587 than 25. to=<@hotmail.com>, relay=none, delay=59728, delays=59668/0.08/60/0, dsn=4.4.1, status=deferred (connect to hotmail-com.olc.protection.outlook.com[104.47.40.33]:25: Connection timed out) connect to hotmail-com.olc.protection.outlook.com[104.47.41.33]:25: Connection timed out connect to hotmail-com.olc.protection.outlook.com[104.47.40.33]:25: Connection timed out to=<@hotmail.com>, relay=none, delay=59728, delays=59668/0.08/60/0, dsn=4.4.1, status=deferred (connect to hotmail-com.olc.protection.outlook.com[104.47.40.33]:25: Connection timed out) connect to hotmail-com.olc.protection.outlook.com[104.47.41.33]:25: Connection timed out connect to hotmail-com.olc.protection.outlook.com[104.47.40.33]:25: Connection timed out Here is my master conf. submission inet n - - - - smtpd -o syslog_name=postfix/submission -o smtpd_tls_security_level=encrypt -o smtpd_sasl_auth_enable=yes -o smtpd_client_restrictions=permit_sasl_authenticated,reject -o smtpd_recipient_restrictions=reject_non_fqdn_recipient,reject_unknown_recipient_domain,permit_mynetworks,permit_sasl_authenticated,reject -o content_filter=smtp-amavis:[127.0.0.1]:10026
What operating system? Are you using ISPConfig, which version? What log is the one you pasted in the original message? It does not look like postix log in /var/log/mail.log, which I would look at first. Are all adresses failing when sending or only to that one address?
I am using Ubuntu; No. Im not using ISPConfig. Never heard of it. Yes, that is a /var/long.mail.log Only one IP.
Also had a similar problem. Contact your server company and make sure they don't have that port blocked.
even on port 587? when i hit the submit button the message is sent over 25 not 587. Nothing is going out on 587. thats my issue.thanks
The postfix conf you posted looks like nothing is set up to change the default port. I'm confused as to what is the question you want answered? In case you can not use port 25 for outgoing e-mails, you can use relay host. Use the relay_host setting in postfix. Is that what you wanted to know?
I uploaded my main and master file. I wasn't aware I had to relay my connection to use port 587. I m trying to setup a mail server using one server with clients connecting to that server.
