Reverse alias in mail body about app

@SibrenVasse Nice catch! I have actually thought about this before and am not 100% sure that removing all "traces" of SimpleLogin is a good idea:

• SimpleLogin tries to never touch the email body as this is a tricky topic: email clients are famous to create messy email body.
• one can always see that the emails are coming from SimpleLogin by looking at the email header
• the reply-email can only be used by its authorised users (i.e. alias owner).

But if this feature makes sense for a lot of users, we could add an option to remove all SimpleLogin traces from the email.

@SibrenVasse I have tried to replace the [email protected] (the code is on the branch staging) and it works well :). , except for the case where emails are signed (via PGP): the signature fails as email content has been modified.

Agreed, removing all traces from the mail body is not necessary or in any way a information / or security issue (your third point)
It's just a visual thing that in my case the email thread was confusing people as who sent what email.

I think just replacing the [email protected] string would go a long way though. As this string is very unique and will never occur in an email normally, so should be safe to find and replace, no matter the messy email body?
