Delayed Mail (still being retried)

Mickelin

I installed the Mailcow Email in our Cloudpanel by following this link
https://www.cloudpanel.io/docs/v2/guides/applications/mailcow/

but we are facing issues with….

1) Can’t receive emails sometimes received

2) Emails are in Queue manager having error as

temporarily suspended: connect to alt4.gmail-smtp-in.l.google.com[108.177.104.26]:25: Connection timed out)

3) Received emails as “Delayed Mail (still being retried)”

Is there anyone can help to resolve this issue..

Thanks

Seems like your provider is blocking port 25 outgoing.

Mickelin

Thanks for your support.. but Port 25 is enabled

Mickelin but Port 25 is enabled

Port 25 incoming maybe, but check if port 25 outgoing is allowed. Install telnet on your machine and check it, should look like this:

telnet smtp.google.com 25

Trying 2a00:1450:4013:c02::1b...
Connected to smtp.google.com.
Escape character is '^]'

That is IPv6. Can you try with googles mailserver IPv4 108.177.104.26 also?
