After the update to 64, email forwarding to gmail accounts stopped working. This same thing happened about a month ago after an update, but a few days later, you updated again, and fixed it. The server connects to google: Connecting to gmail-smtp-in.l.google.com [74.125.70.27]:25 ... connected But then it just sits and spins for 30 minutes, before finally Timing Out: (110): Connection timed out H=alt4.gmail-smtp-in.l.google.com [209.85.202.27]: SMTP timeout after end of data (138195 bytes written)

  cPanel Support was able to figure this out: The following bug in Exim was not adding a final newline to messages using BDAT: Bug 1974 " Handle missing final CRLF in chunked/BDAT transferred messages, resulting in a missing final LF in spool files In cPanel 62 chunking was disabled as a workaround for this bug, however, I'm not seeing in your server's Exim configuration chunking being disabled. I have opened an internal case CPANEL-12403 for this and as a workaround in the mean time I have disabled chunking through Exim's Advanced Configuration Editor.

  Hello, To update, Exim 4.89 was included in cPanel 64 with chunking enabled again, however the Exim changes were not sufficient and still lead to issues like the one reported in this thread. We're disabling chunking again (CPANEL-12403) to address this issue. I'll update this thread again once the change is published. Thank you.

  Hello, Exim was updated to revert chunking support in a recent cPanel 64 build. Here's an example of the output you should see when checking to confirm that chunking support is disabled:
  # cat /usr/local/cpanel/version 11.64.0.11 # grep -i chunking /etc/exim.conf chunking_advertise_hosts = 198.51.100.1 hosts_try_chunking = 198.51.100.1 hosts_try_chunking = 198.51.100.1
  This should address the issue reported on this thread. Thank you.
