Hi,

I did read a few threads on bounce email and it seems to be affecting my server too..

I'm seeing gradual increase in exim que.. currently it is at 600+ emails..

I used ConfigServer Mail Queues to check it shows some thing like this(of course few hundred)..

Code:
1VMfFQ-0002lJ-7K		24h	9.8K	[bounce]	[email protected]
1VMfFQ-0002lT-BK		24h	9.8K	[bounce]	[email protected]
1VMfGQ-0002nm-4H		24h	106K	[bounce]	[email protected]
1VMfI0-0002qO-C7		24h	106K	[bounce]	[email protected]
1VMfJR-0002rz-Q5		24h	106K	[bounce]	[email protected]
I opened one of the mail and here is the header..

Code:
1VMfFQ-0002lJ-7K-H
mailnull 47 12

I'm already using ConfigServer Mail Queues to view and deleting bounce emails.

But, how to solve this issue? The mail que starts to fill with bounce emails again in a few hours.

pl help.

Check with the Spam origin. Suspect there should be spam sent previously from the server. Now you shoule be receiving more bounce backs. You can identify those as the frozen mails in the exim mail queue.

Can you try # exim -bpr | grep frozen | wc -l

Can you post the output here ?
