Verification email not getting sent on self hosted instance

Hi, I’ve setup Penpot on a VPS using CapRover single click apps. Issue is, after I try creating an account, it says it has sent me a verification email, but I receive not such email. My configuration is the following:

PENPOT_PUBLIC_URI=
PENPOT_TELEMETRY_ENABLED=false
PENPOT_SMTP_DEFAULT_FROM=REDACTED
PENPOT_SMTP_DEFAULT_REPLY_TO=REDACTED
PENPOT_SMTP_HOST=smtp.purelymail.com
PENPOT_SMTP_PORT=465
PENPOT_SMTP_USERNAME=REDACTED
PENPOT_SMTP_PASSWORD=REDACTED
PENPOT_SMTP_TLS=true
PENPOT_SMTP_SSL=false
PENPOT_DATABASE_URI=postgresql://srv-captain--penpot-postgres/penpot
PENPOT_DATABASE_USERNAME=penpot
PENPOT_DATABASE_PASSWORD=REDACTED
PENPOT_REDIS_URI=redis://srv-captain--penpot-redis:6379/0
PENPOT_ASSETS_STORAGE_BACKEND=assets-fs
PENPOT_STORAGE_ASSETS_FS_DIRECTORY=/opt/data/assets
PENPOT_FLAGS=enable-registration enable-login enable-log-emails enable-smtp
PENPOT_REGISTRATION_DOMAIN_WHITELIST=
PENPOT_TENANT=pro

Is there something wrong with my configuration, or is there any way to disable email verification?
