I have this error : SMTP error (550) - 5.1.1 recipient adress rejected .
I receive all mails well but when I try to send, it’s impossible (with roundcube web and also with thunderbird with my MIAB parameters).
It’s making this error for 1 month, before, all was working well …
Any help please ?
I see the domain “free.fr” in your error message and this doesn’t look like what I would expect from a MIAB setup. Can you give me the MIAB hostname? On this error alone, I get the feeling you’ve overlapped with a different domain somehow
$ dig mx free.fr
; <<>> DiG 9.16.22-Debian <<>> mx free.fr

$ nslookup mx1.free.fr
It’s the same with all the mail domains => I can’t send but receive well…
“SMTP error (550) - 5.1.1 recipient address rejected”
covers a lot of ground.
My first thought is that you are on a blacklist. Have you changed anything recently?
You are right : I am blacklisted
I 've just made a request on Drone BL to remove my IP from blacklist…
I wouldn’t concern myself with UCEPROTECT.
I always check using DNSBL.info as they seem to check more lists than most other tools:
/var/log/mail.log for responses from the other servers that are rejecting you. They often provide responses in the transaction messages.
