Isn't there anything I can do? It's a major provider in our country ...
Today I heard from some people they got a bunch of mails today. So they got delayed with a few days
What about greylisting (for sending mail) and Plesk's Qmail implementation? Is it supported by default?
As the only thing I heard from some other users is that they have implemented greylisting. Should I change any "retry time" setting or so?
Btw: xxx.xx are two different hosts of course in my previous message. Just to make sure:
Hi. This is the qmail-send program at yyy.yy.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
xxx.xxx.xxx.xx does not like recipient.
Remote host said: 450 <email@example.com>: Recipient address rejected: Try again later
Giving up on xxx.xxx.xxx.xx.
I'm not going to try again; this message has been in the queue too long.
--- Below this line is a copy of the message.
yyy.yy = my server
xxx.xx = recipient
