I want to gradually move from my primary email address that I use everywhere, to a new email with my own domain.
Because this will a while to move all my accounts to this new email, I wanted to forward messages from the old email to the new one.
The issue is that my old email provider doesnt support forwarding.
I am using Zoho as my mail hosting for my new domain and like Gmail, it provides a way to connect to an existing IMAP server. The problem is that it creates a separate Inbox and their filters system doesn't work with this IMAP setup. I want a single inbox and with advanced filter capabilities.
I am experimenting go-getmail, which is a tool that allows syncing between two IMAP servers and it works quite well. I managed to get all my emails in a single inbox working. but Zoho filters don´t work with IMAP.
So, I tried modifying the library to read incoming messages from my old email via IMAP and then forward them to my new Email Account using SMTP.
It works and filters are applied. The problem is that most messages now are going to SPAM because of failed SPF checks.
I read about SRS, but If I understood correctly, it works at server level, which I dont have access to. I am just using an SMTP client to forward the messages.
So, my question is, is there any order way I can around to forward messages from my old email or I am really stuck into it, or using other email providers as clients via IMAP?
Thanks.
