@wrx7m said in Postfix on Fedora 29 - Why Can't I Send Mail?:
I am setting up Postfix on Fedora 29 to send notifications for dnf-automatic and fail2ban. This server is running on Vultr and I am trying to send from DomainB.com to DomainA.com. DomainB is a new domain that hasn't been used for anything and DomainA is our main email domain, setup on Office 365.
In the postfix logs, I am getting connection timed out -
Mar 18 17:19:41 HOSTNAME postfix/qmgr: EEE853EE90: from=<[email protected]>, size=465, nrcpt=1 (queue active)
Mar 18 17:20:11 HOSTNAME postfix/smtp: connect to domainA-com.mail.protection.outlook.com[184.108.40.206]:25: Connection timed out
I have tried disabling firewalld, but still have the same issue. Not sure where the hangup is. Any suggestions on what to check?
I just went through this on Friday
