### Description
When I enable the IMAP Extension and have Tailscale DNS on, basic php -v takes 5
seconds.
I am not running ANY PHP code. Just showing the version
## With Tailscale DNS + Imap
```
❯ time php -v

### With Tailscale DNS **Without Imap**
```

Does the imap extension some DNS stuff on extension start which triggers this behaviour?
