Mails sended from OJS platform are rejected by many servers with the following error:
25: SMTP error from remote mail server after RCPT TO:<firstname.lastname@example.org>: 450 4.7.1 Client host rejected: cannot find your reverse hostname, [188.8.131.52]
I tryed differend configuration like configure an envelope-sender but there is no result.
Which OJS version are you running? And when you configured the envelope sender, did you ensure that your principal contact email address matched that of your server domain?
Running OJS 184.108.40.206
When configuring envelope the sender was from the domain (cude.es)
; Allow envelope sender to be specified
; (may not be possible with some server configurations)
allow_envelope_sender = On
; Default envelope sender to use if none is specified elsewhere
default_envelope_sender = email@example.com
; Force the default envelope sender (if present)
; This is useful if setting up a site-wide noreply address
; The reply-to field will be set with the reply-to or from address.
force_default_envelope_sender = On
Did you set a SPF(Sender Policy Framework) entry record in your DNS domain zone?
It might not be related to OJS but how your server is set to send emails.

I will contact with our provider in order to know if it is possible.
My internet provider did the change but the problema continue…
25: SMTP error from remote mail server after RCPT TO: firstname.lastname@example.org ;: 450 4.7.1 Client host rejected: cannot find your reverse hostname, [220.127.116.11]
It seems that they also need set your reverse DNS, I tested your IP server and it returns not found for reverse DNS:
$ host 18.104.22.168
Host 10.189.138.62.in-addr.arpa. not found: 3(NXDOMAIN)
Otherwise, in your response sample, if I test
uam.es name it is working:
$ host uam.es
uam.es has address 22.214.171.124
uam.es mail is handled by 10 smtp.uam.es.
Please, check with your hosting provider this setting.
I told to my internet provider to make the change, I tell you when done…
