MTA mail problem

[Osman_Tuncbilek]

Hello,

We have an error from maillog file  in Sandblast appliance.

Some attachment mails are not sending correctly.

Do you have any idea about the issue?

"from" and "to" information looks changing in maillogs.

I believe this is being posted in the wrong area - this is the board for SandBlast Now, where everything is automated and you wouldn't be seeing any logs because there's no console.
