I have a new exim4 server and I need to forward some addresses to a gmail address.
support@myeximdomain.com --> mysupport@gmail.com
I have created the router with driver = redirect and everything seems to work on exim side. This is the router:
sender_redirect:
driver = redirect
data = ${lookup{$sender_address}lsearch{/etc/exim4/sender_redirects}}
however Gmail is refusing all emails with this error:
Server returned '<gmail-smtp-in.l.google.com #5.0.0 smtp; 550-5.7.1 [xx.xx.xx.xx] Our system has detected that this message is likely suspicious due to the very low reputation of the sending IP address. To best protect our users from spam, the message has been blocked. Please visit https://support.google.com/mail/answer/188131 for more information
My IP address is just given from the provider, and it is new and seems not included in any blacklist. I have tried to check the support link and, as far as I understand, I have to be sure exim is not breaking the envelope. Is this exim configuration breaking the evenlope? Can I do something?
