I own a personal domain for my university's alumni association and would like to create email addresses for various associated personnel.
e.g. email@example.com, firstname.lastname@example.org, email@example.com
Now, an easy way to do this would be to have them configure the "Send mail as" option in their personal email accounts, allowing them to send email from their own inboxes with the custom email addresses. The hosting server could be configured to forward all email sent to firstname.lastname@example.org to email@example.com.
The tricky bit is, that after 2 years, an electoral process takes place and new personnel replaces the previous one. I'm looking for a solution by which after 2 years, the outgoing personnel could no longer use their custom email addresses.
Is this possible, or do I need to set up separate email accounts for this?
Perhaps someone with experience in this matter could help me with this, since I don't have the slightest clue...
