We are sending large email blasts (5,000+) and more than 1,000 of our subscribers have yahoo.com email accounts.
CiviMail works well now, and most emails go out quickly on our dedicated server. Except for yahoo which takes several hours or even several days to get out of the smtp queue.
I am working with yahoo, and they said they made some changes to their system for our IP address (did not seem to help much), but they also recommand:
1- to send only 5 messages at a time or at least to have SMTP reconnect automatically after 5 messages and being dropped by them
2- to use multiple concurrent connections
On our CentOS system, we use Exim as our SMTP server, but I am not familiar with it.
Any idea on how to better setup either CiviMail or preferably Exim/SMTP to accomodate Yahoo?
Thanks

Yes, as far as civimail is concerned, it thinks that the emails are gone, and the reports reflcet that. In reality, they go to the "transport" program that does the actual sending over the internet. In my case, Exim which is an SMTP server. It has its own queue and commands to look and manage.
I use cpanel so i just look at the smtp queue there (like that i do not need to remember the syntax of all the command line commands for ech system...)

FWIW – mailq seems to be the generally-accepted standard.
