The way the sqwebmail sends it's gpg content in attachments is the same type that Evolution email uses, bit I have seen other email programs that put the gpg content right into the email. What are the names of the two different standards?
sqwebmail uses MIME/PGP, as defined by RFC 2015.
The other one is inline PGP, which how things used to work before MIME came into existence.
pgp00000.pgp
