I've ported my mail server to a new host and cannot get the new install of roundcube to send email. The old host is running Debian 6 with an older versions of roundcube, dovecot, postfix and apache2. The new host is running the latest Debian 10. Roundcube is installed as a Debian package.
Postfix is running fine, I can connect and send mail from 3 different email clients.
When I try to send from Roundcube I get tls errors.
Out: 220 mail.dannelson.net ESMTP
In: EHLO [10.1.1.8]
Out: 250-mail.dannelson.net
Out: 250-PIPELINING
Out: 250-SIZE 50000000
Out: 250-VRFY
Out: 250-ETRN
Out: 250-STARTTLS
Out: 250-ENHANCEDSTATUSCODES
Out: 250-8BITMIME
Out: 250-DSN
Out: 250 CHUNKING
In: STARTTLS
Out: 454 4.7.0 TLS not available due to local problem
I get similar messages in other log files.
It looks like a Postfix problem, but the certificates look ok and configured such that 3 different email clients work with it.
I thought I'd point roundcube to the old host to see if I could send mail through it. Same problem. Yet roundcube on the old host talks to postfix on the old host without problem.
Roundcube is configured to use tls. I think I've tried every configuration setting but I'm getting nowhere. I've been trying to get this going for several days now with no success. If I can't get this to work my next step is to uninstall the roundcube package and install it from source.
Any suggestions would be helpful.
Thanks

What type of certificate is your SMTP server using. It could be a cert verification error. Have a look at https://github.com/roundcube/roundcubemail/wiki/FAQ#problems-connecting-imapsmtp-server-via-ssltls
Thanks for the reply. I think you're right, it has something to do with certificates. I've tried several different things. I'm currently using the certificates that I used on the old host.
I'll check out the link that you gave me, I've had a quick look and it looks promising. Will have a chance to work on it later tonight.
