Hello, as Gmail is often putting e-mails from me into recipients' Spam folder, and there seems to be no solution for this (I tried everything to no avail), I'm considering an idea of sending e-mail to Gmail users via Gmail server, with help of a Gmail account specially created for that purpose. (If that doesn't help then - I guess - nothing helps :( ).
I have a few questions regarding how to configure this in Postfix. 1) It's obvious that Postfix has to authenticate to Google SMTP server to submit mail through it (with credentials of that specially-created Gmail account). However, I found in the Postfix docs that SMTP client authentication works only with Cyrus SASL module, not with Dovecot one. I have currently Dovecot SASL configured, as Dovecot is running as my IMAP server, and I don't want to change that. Is it possible to have both SASL modules (Cyrus and Dovecot) installed and working simultaneously? Or to have Cyrus module working with Dovecot IMAP server? Well, it is actually more a generic Linux question than Postfix-specific, but I hope someone here will be able to answer :) 2) Assuming I have SMTP client authentication working, now I have to setup transport_maps (and smtp_sasl_password_maps) so that only mail to Gmail is sent through Gmail server. And here is some tricky part. While putting the gmail.com domain explicitly as a key in transport(5) table is no problem, there is a multitude of companies that are using G Suite and have Gmail-hosted mail with their own domain, and I experience the same issue with them (ie. my mail being put to Spam by Gmail). So there's a need to check if the MX for a destination domain is within google.com or googlemail.com domain, and if yes, to send mail via Gmail server as well. Is there any way to do it with transport_maps ? -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub."
