Hello,
so this is the scenario:
many of my customers use their email from work (not a problem due mostly static IPs at companies) and from their smartphone and/or homes.
problem is, while connected to 3G/4G or through a home ADSL, the IP is dynamic and in spam lists most of the time (thx to lame spanish ISPs), most of the mail they send is considered as spam even when they send email to coworkers inside their own domain.
the only solutions i have found, is if every user adds them manually to their whitelist.
this is a big hazzle and unacceptable.
i need a way so inside a domain, i can whitelist all emails that come from the same domain. i am using smtp auth, so this should not be a problem.
how can i achieve this?
