Bug ID: 2885 Summary: Emails to Gmail receive "Remote host closed connection in response to end of data" (4.94.2 ok) Product: Exim Version: 4.95 Hardware: x86 OS: Linux Status: NEW Severity: bug Priority: medium Component: Delivery in general Assignee: unalloca...@exim.org Reporter: gibbatheh...@gmail.com CC: exim-dev@exim.org We've tried upgrading from Exim 4.94.2-2 to 4.95-2. 4.94.2 is good, 4.95-2 produces the errors. Emails to places like hotmail/Outlook/Yahoo etc are all fine. Emails to gmail produce the message "Remote host closed connection in response to end of data" It seems to try several times, rotating through gmails alt servers. I.e full messages for a single email send may be... <id> <= <sourceemail> U=<username> P=local S=25937 <id> H=gmail-smtp-in.l.google.com [142.251.5.26]: Remote host closed connection in response to end of data <id> H=alt1.gmail-smtp-in.l.google.com [142.250.153.27]: Remote host closed connection in response to end of data <id> H=alt2.gmail-smtp-in.l.google.com [142.251.9.26]: Remote host closed connection in response to end of data <id> H=alt3.gmail-smtp-in.l.google.com [142.250.150.26]: Remote host closed connection in response to end of data <id> H=alt4.gmail-smtp-in.l.google.com [74.125.200.27]: Remote host closed connection in response to end of data <id> <receipientemail>R=dnslookup T=remote_smtp defer (-18) H=alt4.gmail-smtp-in.l.google.com [74.125.200.27]: Remote host closed connection in response to end of data Maybe 20 mins later it can sometimes go through with...
