I'm trying to increase the MTA timeout on ZCS 8.0.4 Open Source - it looks like it's set to 30 seconds by default. Which command or attribute is used to change this? I'm going to be sending email to a domain that has a server which is regularly busy and may take longer than the 30 seconds to respond, so I want to increase this timeout.
Here is an excerpt from my zimbra.log that shows the 30 second timeout:
