In MailMate, you can set up automatic Bcc: addresses for outgoing emails. For each messages, you can add other blind carbon copy recipients, of course, or remove the defaults.
Automatically Bcc: An Address On Every Email You Send in MailMate
To send a blind carbon copy of every email from MailMate to a certain email address automatically:
- Quit MailMate.
- Launch Terminal.
- Type "defaults write com.freron.MailMate MmDefaultBccHeader -string " (not including the quotation marks) followed by the email address to which you want the automatic Bcc copies to go.
- If you want to Bcc: bcc@example.com, for instance, make sure the line reads
'defaults write com.freron.MailMate MmDefaultBccHeader -string bcc@example.com' (not including the quotation marks). - Note that the new address will replace any existing automatic Bcc: headers in MailMate.
- To add more than one automatic Bcc address, separate them by comma and surround them with quotation marks. To add both bcc@example.com and copy@exampl.com, e.g., make the line read
'defaults write com.freron.MailMate MmDefaultBccHeader -string "bcc@example.com,copy@example.com"' (not including, this time, the outer, single quotation marks).
- If you want to Bcc: bcc@example.com, for instance, make sure the line reads
- Press Enter.
- Quit Terminal.
The addresses will automatically appear in the Bcc: field as you start composing new messages in MailMate. You can remove them, of course, or add further addresses to the list for individual messages.
