Hi,

It is not possible to stop bouncing emails as they are increasing in the queue.

How can I solve this problem, please help.

Hello :)

The messages are bounced because of the SPAM content. Here is the relevant bounce message from the remote server:

The mail server detected your message as spam and has prevented delivery (150)
This seems like an accurate message based on the message content you provided. You should determine the source of the SPAM and implement methods of reducing the amount of SPAM coming from your system. There is a guide on this at:

cPanel - Prevent Email Abuse

Thank you.

With all due respect, there is a better method of handling mail that triggers a specific spam threshold. You should never be bouncing spam.

In Exim Configuration Manager:

ACL Options: SpamAssassin™ reject spam score threshold [?] - set this to 15
- it looks like you currently have this DISabled

Filters: SpamAssassin™: bounce spam score threshold [?] -- choose "no bouncing by spam score"
- it looks like you currently have this ENabled with a score of 15

The Filters bounce, the ACLs reject during SMTP. Rejecting during SMTP is always better than accepting/bouncing.

Basically, if you set up the 'bouncing', then you will accept the mail and then attempt to bounce it back to the [usually] forged sender. If you reject [during SMTP], then you won't be bouncing spam back to people who never sent it and you won't have the mail queue building up with so many undeliverable emails.

You might also want to consider setting that value lower (10). Then again, I'm in the US. Depending upon where you are, you may actually receive a number of legitimate emails with a spam score of 10-15.
