How to tell number of silent drops due to DHAP?

Unanswered Question
Feb 1st, 2008

Hi, does anyone know how to tell the number of silently dropped connections because DHAP threshold was reached (for the hour)?

Because lately, we've been getting so many invalid recipients from, and I'm a bit worried that some legitimate emails are not getting through because of DHAP and having the option "drop connection if DHAP threashold is reached" in the SMTP conversation enabled.

I check in the GUI (Ironport C100 ver 4.7) "Rejected Connections" for, and there are 0 rejected connections. Are silent drops due to DHAP counted as connection rejections or not?

Thank you.

I have this problem too.

Most of this information should be contained in the mail logs. I would recommend getting the mail logs and grepping for string 'dhap_limit'. You can refine the grep search to search for data within a specific hour.
