Question

Email Greylisting bypass with WHM, cPanel?

Asked by: Cem

Currently alot of emails get stuck in mail queue with message "your ip has been greylisted, please come back in 2 minutes".

Is there any possible way to make server understand these messages and automatically retry after 2 minutes? So they wouldnt get stuck. I tried to change delivery time to 5 mins (default 60) in WHM tweak settings. However they get still stuck for like 24 - 72 hours.

Aswell some mails get stuck in mail queue when user mailbox is full. Is there way to answer immediately "mailbox full error" to sender and dump whole sent message?

Hi,

Please do the following to prevent from these probblem.

1. Disable spamassign from the Tweak setting and exim configuration editor.
2. Once disable the disk quata so all mails will be deliver to the client folder without checking the quata.

If you have enable disk quata and bounce back mail option then mails server will be bounce back message with the mail box size exceeded to the sender.  It look like queue is full so clients are not getting any bounce back message.

so you're talking about *your* mail which was not delivered on a remote mail server?
if so, you need to configure the timeout of your MTA to resend mails from the queue.
