Cant connect to external mail

[insha]

Hi, after i have upgrade server and also Previously in beta using this:

https://help.directadmin.com/item.php?id=408

I cant connect my mails to external apps like sparkpost (android)
Mozilla thunderbird (Windows pc)
It doesnt accept my server Hostname as mail address, ports.
How can i fix this, or get Away from beta directadmin, stay in stable version?

To go back to stable do this

https://help.directadmin.com/item.php?id=29

don't forget the last line

Note Pre-release and regular updates to not issue full config rewrites. If you need a template change, you must issue a full rewrite to get it:

cd /usr/local/directadmin/custombuild
./build rewrite_confs

Also once you have moved back to stable. Please make sure your options.conf is correct.

cat /usr/local/directadmin/custombuild/options.conf

If it is all correct I would do a

cd /usr/local/directadmin/custombuild
./build update
./build all

just to be safe.
