Re: OpenSMTPD is not sending e-mail.
Hi, a few days ago all my boxes using the same ISP stopped to send me emails from local users and daemons (daily outputs and any other cronjob reports) to @gmail.com. I have tried to send email to a few not_gmail mailboxes - the same problem. If i send emails from other boxes (using other ISP), they are received correctly. Telnet test doesn't show the "220 mx.google." line. Does is mean that port 25 is blocked by the ISP? $ telnet gmail-smtp-in.l.google.com 25 Trying 173.194.220.26...

Vultr isn't my only VPS provider but I definitely recommend them. When I submitted a ticket requesting they open port 25, they responded within minutes on a weekend. BTW that info about 25 (and a few other ports I believe) being blocked by default is somewhere on their website. Mitch

Re: OpenSMTPD is not sending e-mail.
Hello misc@ I can not believe that the solution has been to open port 25, Vultr rent servers whit port 25 closed! Thanks so much to Stuart Henderson for the solution.

What do you get if you type "telnet gmail-smtp-in.l.google.com 25"? It should go something like this: $ telnet gmail-smtp-in.l.google.com 25 Trying 66.102.1.27...

Re: OpenSMTPD is not sending e-mail.
Hello misc@ From smtpd.conf Man Page: "EXAMPLES The default smtpd.conf file which ships with OpenBSD listens on the loopback network interface (lo0) and allows for mail from users and daemons on the local machine, as well as permitting email to remote servers. Some more complex configurations are given below." It had worked for many years; but this time OpenBSD 6.8; server and Laptop, are not working as the man page says. I did an empiric test, because i am not qualified for a real test. Both are not able to send messages (e-mails), to other machines. The message at maillog is the same: result="TempFail" stat="Network error on destination MXs" I did 2 clean installations; one server, and one laptop; then i sended one message from server to Laptop, and viceverse. The message in both is the same. It was after this change in smtpd.conf: match from any for domain "agroena.org" action "local_mail" If i send an e-mail from other machine, it is received correctly. Is it possible that something is wrong in my installations? Thanks for your attention.

You haven't given much log output, but "Network error on destination MXs" usually indicates something like DNS or network issues.
