Hi,
yes, on the compose screen. at = @
I had to rewrite the email address, because the forum (software) told me: "Sorry, you are not allowed to post external links"
I can not reproduce the error. Now it is working fine ... I don't know what happend. Maybe I only need more sleep.
By the way: thank you for aqua-mail. For me the best email client on the market and it is worth every cent.
