Hi, Likely a noob issue, apologies! I’ve been trying to migrate from a simple SendGrid Swoosh adaptor to an SMTP one, as I’ve switched over to Zoho mail. I can’t get an email to fire, but I can get it to work using a simple Python script, so I know the account setup and auth stuff is fine, I just c…

I wonder if you could try Mua adapter, in the very least it would show the actual error message: Swoosh.Adapters.Mua — Swoosh v1.26.2 (note the extra deps) config :embernotes, Embernotes.Mailer, adapter: Swoosh.Adapters.Mua relay: "smtp.zoho.eu", auth: [username: "username", password: "passwo…

:wave: @stefannovak Do you get any warnings from Erlang before this :retries_exceeded error?

https://github.com/gen-smtp/gen_smtp/issues/298#issuecomment-1405328435 The options don‘t do well separating starttls from fully tls connections.

But Zoho seems to be “normal” STARTTLS # doesn't work $ openssl s_client -connect smtp.zoho.eu:587 # works $ openssl s_client -starttls smtp -crlf -connect smtp.zoho.eu:587 So I would try this config: config :embernotes, Embernotes.Mailer, adapter: Swoosh.Adapters.SMTP, relay: "smtp.zoho.eu"…

Hey guys thanks for the responses! No Erlang error before this error, it’s just a GenServer crashing when it occurs after trying to send an email. [error] GenServer #PID<0.1442.0> terminating ** (MatchError) no match of right hand side value: {:error, {:retries_exceeded, {:missing_requirement, ~c"…

[image] stefannovak: I wrote that after failing to get an elixir script going, just wanted to see if any other language/framework could get it working, which made me believe it’s a Phoenix specific issue. Highly unlikely, most probably the option for authentication you are trying to use is in…

Oh, actually the new error is different, so one of the tls_options worked :slight_smile: The error now is {:missing_requirement, ~c"185.230.214.164", :auth} and before it was {:temporary_failure, ~c"185.230.214.164", :tls_failed}, so now it’s about :username and :password options.

Sorry, i didn’t mean Phoenix itself, just my configuration with it

Apologies, I pasted the wrong thing. I was experimenting with turning TLS off (frustration i guess haha) and pasted that result in, instead of the usual :tls_failed error

Stuck setting up SMTP, TLS issues
