Hello,
We're a UK ISP, and relay email for our customers as well as send our
customers emails such as invoices.
We currently have about 1,000 emails queued for google accounts and
these are failing with a timeout, eg from exim:
2021-12-02 11:48:05 1msize-005feQ-DI H=gmail-smtp-in.l.google.com
[142.250.13.26] TLS error on connection (send): The TLS connection was
non-properly terminated.
2021-12-02 11:48:05 1msize-005feQ-DI H=gmail-smtp-in.l.google.com
[142.250.13.26]: SMTP timeout after sending data block (525043 bytes
written): Connection timed out
Based on past experience, eventually, the emails may will through.
This is also intermittent, as sending to my own gmail address tends to
get through eventually, though they do still time out once or twice
before eventually getting through.
Generally these emails do show as SPF/DKIM/DMARC PASS in gmail.
This report is rather vague, but we do have further examples, logs, pcaps.
Is someone from google on this list able to help investigate this
problem with us please? I can pass examples and pcaps privately.
Thanks!
Andrew, AS20712 aa.net.uk
