Hello
Yesterday, I updated the iRedMail server to 1.6.0 and iRedAdmin Pro 5.2. Also, I converted OS from CentOS 8 to Rocky Linux 8.
A Linux client and several printers, cannot send email through the mail server.
On /var/log/maillog .. I see these logs:
Aug 1 11:09:21 correo postfix/submission/smtpd[1505703]: Anonymous TLS connection established from recamier1x.recamier.com[192.168.20.4]: TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)
Aug 1 11:09:21 correo postfix/submission/smtpd[1505704]: connect from recamier1x.recamier.com[192.168.20.4]
On Mail queue of Linux client .. I see the following message:
(delivery temporarily suspended: lost connection with correo.recamier.com[192.168.20.20] while performing the EHLO handshake)
How can I fix this issue?
Thanks.
