Mail Forward Chaining?
Is it possible to forward mail to email1 then forward it again to email2?
I'm getting an error and I'm not sure if it's Roundcube related or just mail limitations:
Failure Reason: Error: 501 5.1.7 Bad sender address syntax
I've tried multiple filter types in Roundcube but they all end up with a "Message delivery failure notice".
The reason for all this is because the default iOS Mail app sucks at notifications and I'm fowarding mail from all my domains to one Cloudron inbox and then have that forwarded to ProtonMail (their iOS app is awesome and you can set a pass code on the app too!).
@humptydumpty Where do you see this error? If it's in an email, you can inspect the email headers to see why it complains about bad sender address.
@girish Yes, it's in a separate email that I receive after sending a test email.
(mail.mysite.com: domain of mail-vs1-f45.google.com does not designate 220.127.116.11 as permitted sender) receiver=mail.mysite.com; identity=helo; client-ip=18.104.22.168 helo=mail-vs1-f45.google.com; envelope-from=<email@example.com>
@girish Proton support just sent me this..
Unfortunately, ProtonMail doesn't support "Sender Rewriting Scheme (SRS)"
@humptydumpty That does make it hard to forward to protonmail. IIRC, gmail also a type of SRS when forwarding. I guess even that won't work with protonmail.
@girish Noted. Thanks, Girish!
