Thanks for your feedback! Yes the primary reason for it being receive only right now is to combat spam. I am considering options where self-hosted users and cloud users (perhaps as a premium option) will be able to do this though.
One of the big challenges then would be that self hosting outgoing email servers has historically always been tricky thing in terms of email deliverability. A lot of big email providers block entire residential IP ranges, so more often than not emails tend to be delivered straight to spam.
But there are other options I’m considering such as being able to integrate AliasVault with external email servers (e.g. MS365 or Google) for both receiving and sending. Or leaving the receiving as-is but integrating with an external SMTP relay for email sending.
I’m actively working on improving AliasVault and iterating quickly, so all feedback is appreciated. :-)
