Some mails send from some domains were queued in the ASA and delayed for several hours. After I have removed the option of protocol inspection on Security configuration. After that most of the mails were released but still some mails are queued. Can any one suggest a reason for this.</P> Mon, 11 Mar 2019 11:14:45 GMT https://community.cisco.com/t5/network-security/cisco-asa-inbound-mail-get-delayed/m-p/902912#M974662 demith1982 2019-03-11T11:14:45Z Re: Cisco ASA inbound mail get delayed https://community.cisco.com/t5/network-security/cisco-asa-inbound-mail-get-delayed/m-p/902913#M974664 <HTML><HEAD></HEAD><BODY><P>This is a common problem especially with esmtp inspection.
