OK – on a hunch I disabled TLS for ebay.com.  The messages started coming in!  This is a bot curious as a few ebay.com messages did come in, so it seems they have some issues with their certificates across their multiple email servers.  This begs a couple of questions:

1. How to get these incoming connection issues (outgoing for that matter) entered into the logs so the issues are easier to determine?  It is easy enough to find outgoing as I see the messages in my queue and retry manually – but it certainly would be nice to log this error in the regular mainlog or rejectlog for incoming, for outgoing it does generally log an smtp defer with  signal 11.

2. How many of you run no encryption/TLS for smtp server<->smtp server connections?  Can I ensure that clients all use TLS while not using TLS for server to server connections, inbound and outbound?

Thx.

All,

I am getting emails that are seemingly dropped from the inbound processing.  I noticed these as I am an eBay user and my normal emails were not making it to me.  The only entries in my logs are:

2017-04-02 11:40:04 SMTP connection from [66.211.185.191]:37674 I=[10.10.0.150]:25 (TCP/IP connection count

= 1)

rification succeeded]

ing: spam-score-int: 29 (++). spamreject: 200.

That is from mainlog.  No entries in rejectlog or paniclog.  I have this set for logging in my exim.conf:

log_selector = +address_rewrite +all_parents +arguments +connection_reject +delay_delivery +delivery_size +d

nslist_defer +incoming_interface +incoming_port +lost_incoming_connection +queue_run +received_sender +recei

ved_recipients +retry_defer +sender_on_delivery +size_reject +skip_delivery +smtp_confirmation +smtp_connect

ion +smtp_protocol_error +smtp_syntax_error +subject +tls_cipher +tls_peerdn

Unfortunately my logs look no more verbose than ever (I noted this previously with another issue, cannot seem to get more verbose logging – maybe some help there too).  Perhaps the string is wrong somewhere.

exigrep tells me:

root@svr6:/var/log/exim # exigrep 1cukQ1-000LOe-I1 ./*

I am finding the messages in /var/spool/exim/input, the above message is a file called ‘1cukQ1-000LOe-I1-D’.

If it matters in this case I am running FreeBSD.

Thx for any help.
