451 Try again later

Post by s.r » 2009-04-15 08:15

Good time of the day. I configured hMailServer but it got undeliverable message "451 Try again later".

This sending problem is not for all servers (in particular, it is not at gmail.com, but there is at mail.ru)

The recipient mailserver has greylisting enabled...

Normal behaviour. Your server should try again.
Just 'cause I link to a page and say little else doesn't mean I am not being nice.

I saw this.
I have a web-based e-mail client (RoundCube) that does not send messages. But almost from the client Evoluion works. Can there be a problem in this or is it just a coincidence?
What I need to configure RoundCube, to send mail through hMailServer?
Thanks in advance.

You should read the roundcube documents.
If at first you don't succeed, bomb disposal probably isn't for you! ヅ
