[pfx] One user unable to send email
I honestly don't know if this is an issue with Postfix or Roundcube, but I thought I'd start here. I'm running Postfix 3.8.1 on Ubuntu Server 23.10 and I'm hosting a friend's website and email in addition to my own. My problem is, my friend (who usually accesses her email on her phone via Roundcube) is unable to send email, getting a 451 error when she tries. She can receive emails without difficulty. I am able to send and receive emails, both through a conventional mail client (Evolution) and the Roundcube webmail interface. I know there are ways to throttle Postfix, but I can't find them in either main.cf or master.cf. Can anyone offer any insights?

The remote client's TLS client hello message did not list any ciphers that are enabled in your configuation and supported by your server's underlying OpenSSL library. If the client were on the postscreen whitelist, the connection would have been immediately handed off to smtpd(8), well before STARTTLS. Therefore, this was either a blacklisted client, or else a "new" client, whose IP address has either expired from the cache or has never before connected. It could also, for example, be one of the security scanners (shodan, ...) that specifically tests deprecated ciphers. That said, you've provided no information about your configuration: https://www.postfix.org/DEBUG_README.html#mail so more specific advice is not possible. -- Viktor. ___ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org

That's not the right question. The right question is: - How to deliver some users for a domain locally and and some to a remote server? For that, I'd typically configure the domain as a relay domain, and *rewrite* the addresses that should be delivered locally to a local or virtual mailbox (mydestination or virtual_mailbox_domains) domain. My actual preference is to make such domains be virtual alias domains, and rewrite both the forwarded and the local recipients to internal domains, with some forwarded and some delivered locally. But that's a bit more complicated when the relay destination expects unmodified envelope recipients. It may be possible to give the relay recipients *additional* internal addresses and rewrite to that form... -- Viktor. ___ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org

[pfx] Forward mails if user unknown in local recipient table
Hi, I would like to know if i can configure postfix to forward mails if user not found in local recipient table. Usecase: Users are split between LDAP in my server and a remote server for example.com. So if u...@example.com is not present in LDAP it must forward to remote server. Any idea on how i could do this? Thanks. -- Akshay ___ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
