I first build with DISCOURSE\_HOSTNAME=[bbs2.abc.com](http://bbs2.abc.com)
then I change DISCOURSE\_HOSTNAME=[bbs1.abc.com](http://bbs1.abc.com)
But I found that there was an error message when sending the email, and the sender was `bbs2`
But all the links on my website have been replaced with ‘bbs1’, only the email is still from ‘bbs2’`
I tried to destroy and checked the volume and container, confirming that they are no longer available But next time when rebuilding, it will still display ‘bbs2’`
May I ask how to troubleshoot this issue?

I use `find / -iname *bbs2*` with no result
