I've found what was the problem: in my SendGrid account there was Link Branding enabled. But that's little bit strange because it was enabled before moving to the new server and it worked fine.
I cant send any emails with the local emailer. I keep getting this error:
filter:email.send, 139769591261248:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:s23_clnt.c:769:
Any suggestions? I tried https://community.nodebb.org/topic/4323/emailer-via-local-smtp-and-ssl-tls but still no go.
Thanks and kind regards,
@Adam-Poniatowski I would recommend using an emailer plugin instead of local emailer. Try one of these. All of them provide free tiers.
nodebb-plugin-emailer-mailjet nodebb-plugin-emailer-sendgrid nodebb-plugin-emailer-mailgun
I think I found the problem. My IP has been blocked by their spam filters (microsoft). I had it delisted now and I will see where it goes.
I hope its that...
You will have this problem with all email providers if you use local emailer. They just assume it's spam.
nope... still the same issue
Do you have a proper SPF and DKIM configuration for your domain? It is becoming more difficult to effectively send email to major providers without those in place.
I tried the other emailer (nodebb-plugin-emailer-ssl-smtp) and that works... weird, as I had the local emailer working before, when I had it on my freebsd machine (now centos).
Thanks for trying, it is much appreciated
