We have a Email Gateway on my work. Is it possible for an user send an encrypted e-mail? How does he do that
What version of Email Gateway?
E-mail gateway 7.5
Encryption is discussed in the Administrators Guide (meg_750_ag_a_en-us.pdf) from page 254.
There are several options for configuring encryption, but I don't think these can be applied to a "one-off email from a single user".
