Send e-mails via external SMTP relay gateway #61

Closed SergioArbarviro closed 5 months ago

SergioArbarviro commented 10 months ago

Sending e-mails using the internal SMTP server results in many outgoing e-mails being tagged as spam by recipient Internet Service Providers. I recommend to send e-mails via a third-party, external SMTP relay gateway of a services company dedicated to the deliverability of e-mails.

When considering the source code of the e-mails received from the AlirPunkto platform (see below), the e-mails are indeed sent via the Alinto SMTP relay gateway - but from the publicpolicies.cosmopolitical.coop sub-domain, whereas they should originate from the access.cosmopolitical.coop sub-domain.

On 31-May-2024, the sender of the e-mails is admin@alirpunkto.cosmopolitical.coop. This is correct until Issue #69 is solved. Part of the resolution of that issue should be that the sender be changed to admin@access.cosmopolitical.coop
