For our service Melt Mail there happened to be a Postfix error which prohibits forwarding e-mails from Gmail. The SMTP server fails with the message
454 4.7.0 TLS not available due to local problem
The problem was the smtp daemon of Postfix
warning: TLS library problem: 24753:error:2006D080:BIO routines:BIO_new_file:no such file:bss_file.c:172:
The solution was to remove the
smtpd_tls_CAfile
line in the main.cf file.
