Does Virtru support aliases?
That depends. If you use G Suite --- yes. If it's a new alias, be sure to have your G Suite Admin refresh your domain to ensure that your alias is recognized.However, if you don't use G Suite, for you to be able to open an email that was sent to an alias --- the secure message must be opened in the original inbox of the account that message was sent to. Trying to open a message that has been auto-forwarded to a different account won't work and isn't supported.
