What it does
Aster Mail offers hosted email with aliases and mailbox-import features. It documents automatic encryption between Aster accounts and OpenPGP delivery to outside contacts when a public key is available.
Aster Mail’s encryption description distinguishes two cases. Messages between its own accounts are encrypted automatically; outside recipients use OpenPGP when they publish an appropriate key. That distinction matters more than a general encrypted-mail label.
The service also advertises mailbox imports and alternate addresses. If moving established correspondence, first identify which contacts have usable public keys and which will still receive ordinary email. The free offer provides an initial mailbox. Cryptographic and migration claims here are the provider’s published descriptions.
