Some clients uses external mail services like gmail, oficce365 but also want to use server for some webform’s mails sending. And they also create mail account on server.
So I have to create route in exim.conf like :
To tell exim use external smtp for real mail account delivery. Is there an easier way of this? In directadmin panel, I was simply uncheck “Use this server mail account system”
What I would do:
a) Use external SMTP server with your form. If your website runs wordpress it is fine and there are lots of plugins.
b) install exim as usual. Configure DNS spf records and send directly your email through the external server.
If you want your users to create their mailboxes in Hestia and then again in outlook 365… They can, but it is nonsense.
