This problem report is content free, because it neither quantifies the
problem, nor gives specific examples. To report and get help with
performance issues, you must compile detailed statistics, and post
these along with related sample log entries.
- What fraction of email gets through on the first try
- What is the average number of retries for mail that gets delayed
- What fraction eventually bounces
- How much mail is reported as spam by recipients via the various
feedback loops you've signed up for
- What is the age distribution of deferred mail ("qshape deferred"
output)
Are you sending email only to users who requested to receive said email,
or are you running "opt-out" lists?

If my response solves your problem, the best way to thank me is to not
send an "it worked, thanks" follow-up. If you must respond, please put
"It worked, thanks" in the "Subject" so I can delete these quickly.
