Title: Undelivered emails
Post by: bbc on May 06, 2006, 11:05:15 pm

Sent out to a client's list of 17000+ subscribers-
only 1200 opened vs usual 3000
client didn't get it at all at one of his addresses where he's rec'd it from bcentral svc before

Took me a bunch of emails with my hosting co (I have a dedicated server) and got some 1758 error msgs from cat'ing the exim_mainlog.1 file...

can you help me understand these?
here are the various types:
1. no immediate delivery: more than 10 messages received in one connection
2. rejected RCPT Sender verify failed
3. Message is frozen
4. unexpected disconnection while reading SMTP command

also, what do successful ones look like- or would they not show up in that file?

Thanks!

It sounds like your host is running a default cPanel configuration.  Your server will likely benefit from the tweaks noted in the following post:

Also, your "Reconnect every X emails" SMTP option should probably be set to 1000.

Thanks- I already had set the reconnect at 999 (to be safe)
implemented the queue one

got a FAILED on the split_spool one... it referred to a line that already had the same thing but with 'yes' instead of 'true'

Are those the only things you can see that would prevent delivery?  Did all those error msgs I mentioned look normal?

I am not sure about these ones:

2. rejected RCPT Sender verify failed
3. Message is frozen
4. unexpected disconnection while reading SMTP command

I assume #2 means you might have set an invalid bounce or "Send From Email".  On some servers the "Send From Email" and bounce address (or, with bounce disabled, the Admin Email) must be a valid mailbox on your account.

#3 means, I believe, that the message(s) could be sent later.

#4 should not really happen.  Please let me know if it continues.
