It sounds to me that need to configure your email clients to do the switcheroo about from addresses, etc. I use neomutt, which might not be suitable since it's a text only. But I login to my shell. Then I start neomutt and bind keys within my neomuttrc, to then login to another IMAP server (from a list I have setup) and then reply with the correct From address, using either the local smtpd or one on another server. Using smtpd to send really just means sending the right email and credentials, so there is no real problem having many email addresses for one user. I use Dovecot for IMAP and base smtpd. This is assuming that I have understood your problem correctly. Chris Bennett
