Hi! My server keeps mails long time in queue, so some times the queue is like 300 email, even delivery to local domain take so long time. It is possible to set time shorter in some postfix config file?
There are no errors. Problem is only in the day where are a lot of email. At night all emails are sending out form the server and thay are a few seconds in queue. In the day thay are collected in the queue about 20 min and send out, so queue has like 200-300 email. May be postfix can not send more then 20 email in the same time and the queue is growing. May be this is a problem ?
This could be a problem on the remote server - some servers are configured in a way that they only accept a certain amount of emails from another server in a defined amount of time (for example, Yahoo's mailservers). For example, I had to configure our newsletter program to send out just one email per second because otherwise Yahoo's mailservers would block our emails.
