Hi Jorgen,

Hi,

Could you enable "inspect esmtp" and test? Here is a document for your reference:

[Anu M Chacko]

Hi,

Is this taken after enabling esmtp? Also, what is the IP address of the mail server?

Regards,

Anu

[jorgen.hart]

ok...which mails get dropped? Are mails with attachments specifically getting dropped?

[jorgen.hart]

the mails which gets droped comes from kopparberg.eu which i use for testing the mailserver

maybe there are more mails getting dropped i strated the mailserver yesterday

[Anu M Chacko]

From the logs, I dont see anything out of place. Could you run "debug smtp" on the ASA? Note: enable the debug when there isn't a lot of traffic going through the ASA, as it might affect through traffic.

Let me know.

Regards,

Anu

is there any way to turn of the filtering for the mails, because i tested to change the cisco to an simple d-link and the mails are flowing like they should.
