OK guys, how do you enforce TLS with Brightmail?

Created: 09 Apr 2013 • Updated: 09 Apr 2013 | 10 comments

It seems like the whole world has gone crazy with TLS enforce requirements.

We have been running with opportunistic TLS for ages, even before Brightmail and never thought twice about it.  We have other solutions for *real* email encryption.

Recently it seems many companies have "discovered" TLS and they think that this is some kind of a super-duper new tchnology. Some large companies even have entire departments dedicated to TLS.   And then they send us a long list of their domains to which they want us to enforce TLS, or else they won't do business with us.

So I go to Protocols/Domains and add their domains as non-local, with the require TLS option.

But eventually the list of domains there has grown quite large (170 entries currently). And now each time I go to Protocols/Domains, it takes a loooong time to display them.

But that's not the bad part. The bad part is that each time I add a new domain to the list (or edit an existing entry), I start getting alerts from our Brightmail scanner appliances saying that they crashed and/or a bad message was De-queued.

It seems Brightmail can only handle so few entries in the Protocols/Domains list before it starts throwing fits when you add one more entry.

The other option is to attempt TLS on all outbound emails. This is done under that scanner in Administration -> Configuration under the SMTP tab, Advanced Settings and then the Delivery tab. That takes all the guesswork out of it and as long as the recipient's mail server advertises TLS we will send the message using it.


Oh, we have always had the opportunistic TLS for all outgoing email turned on.

But these people want us to Enforce TLS when communicating with them or else they won't do business with us.

I understand that, but as long as their mail servers advertise TLS we will deliver it that way. The only difference between the options is that the email will sit in the Delivery queue if we don't see STARTTLS advertised by their mail server.


Fine, but they insist that we use Forced TLS to them. They don't want mail to be delivered at all if TLS cannot be established.    They don't want to play opportunistic TLS.

Regarding the slow performance, it sounds like you may be running into a resource issue. You may want to try running a repair on the database. This can be done at the command-line interface by running: cc-config database --repair.

Are you running this as a VM or on physical hardware? Are you sure that you are meeting our system requirements?


Physical.  The control center is model 8380 and scanners are 8360.

We don't have any other performance issues per se.

Just this problem with adding new domains or modifying existing domains under Protocols/Domains.

Which version of the SMG software are you running? Also, which web browser are you using?


Version 10.0.1

I use Google Chrome or IE. Shouldn't matter though.

It most certainly matters which browser. Chrome is not supported and may not load all of the elements of the page correctly. We get calls from people using Chrome that see all manner of strange UI behaviour and pop-up warnings that never show up. When using IE, I recommend you use the compatability mode.

I have never heard of customers experiencing slowness on the Domains page, but I have not heard of customers having that many non-local domain entries either. What were the results of the database repair?


OK, I will take your word about Chrome, however I never had any problems with Chrome and Brightmail.

The repair ran briskly and OKed everything.
