SMTP Problem :(

1

Good evening. Guys, I have a problem :slight_smile:
Sending mail to external servers like Yandex.ru does not work.
I read
Problems with mail settings - #46 by sahsanu
I looked, everything seems to be set up correctly. We ran tests on DKIM SPF, etc. Everything is correct.

It goes to Krasfond.ru mailboxes, but not to others.

Domain Krasfond.ru

Port 25 blocked?

i dont think so
telnet mail.krasfond.ru 25
Trying 193.227.240.166…
Connected to mail.krasfond.ru.
Escape character is ‘^]’.
220 krasfond.ru

grep smtp_ports /var/lib/exim4/config.autogenerated
daemon_smtp_ports = 25 : 465 : 587

Not inbound connections to port 25 but outbound connections to port 25.

From your server:

telnet mx.yandex.ru 25

If it works, check Exim’s logs.

exigrep '=>.*yandex' /var/log/exim4/mainlog*

it’s closed :frowning: How to open ? :slight_smile:

Ask to your hosting provider, they are blocking it.
