So sending mails with that address from other ser- vers will probably cause them to end up in some spam folder or being discarded, with the recipients probably having very little to no chance in hell to persuade their administrators to accept your mails. So, personally, I wouldn't invest any energy in that direc- tion because that is a battle that you cannot win and if you use that mail address for work, i. e. those mails are impor- tant, you need a (reasonably) reliable solution.
