Hi - I am looking at transferring my .com domain to Dynu. I also will need full service email, i.e. IMAP/SMTP.

My question is addressing. I currently use something like Dynu's "Plus Addressing", i.e. John+amazon@yourdomain.com. However, I use "4", not "+".

Per Dynu documentation, it looks like the "Plus Address Character" can be changed. Can it be a "4"?

Thank you
