Mailer speed? (subscriptions)

I've noticed that the mailer seems to have severe "hiccups" in delivering email updating me of subscribed threads. This also affects the DT mailing list as well, regularly ("Daily Defense News Update").
This does not seem to be an issue of the DT server itself, but rather of your provider's SMTP server.

As an extreme example, i received a subscribed thread email today with the following timestamps in the header:
  • Received: from 208.43.29.26 (EHLO itech.invisiontechs.com) (208.43.29.26) by mta451.mail.re4.yahoo.com with SMTP; Sat, 21 Mar 2009 19:29:00 -0700
  • Received: from nobody by itech.invisiontechs.com with local (Exim 4.69) (envelope-from <[email protected]>) id [...] for
    [...]; Thu, 25 Dec 2008 07:19:44 -0600

From the above, that email sat in the queue of that mail server for 4 months, which seems a bit... crass.
And it's not like it's only that one, it's a pretty regular occurence.

Might have to do with your smtp provider's spam settings?

Note 1: I'm currently subscribed for email updates to about 520 threads on DT. All subscriptions are set to "instant".
Note 2: The above example is for this post, to verify that it's not just some timestamp issue.

That is an interesting discovery, I've never seen that as I usually get notifications on my blackberry and its pretty instant.

I will check settings again see what we can find... the newsletter goes to about 25,000 email addresses, I bet the slowness is caused by that somehow.

Thanks!

To clarify a bit: It's a "hiccup" as only some emails stay in the queue for a long time, while others get delivered instantly in the meantime. And those emails then get pumped out often in a single push it seems, perhaps occuring once per month.

This happens a bit more with the mailing list than with subscribed threads actually.

The last 14 mailing list mails i've received were, in that order:

for 02/12/09 - yesterday (03/21/09)
for 02/09/09 - yesterday
for 03/20/09 - on 03/20/09 (right on time)
for 01/21/09 - on 03/19/09
for 01/09/09 - on 03/19/09
for 02/16/09 - on 03/17/09
for 10/22/08 - on 03/17/09 (after five months!)
for 02/23/09 - on 03/16/09
for 02/11/09 - on 03/15/09
for 02/24/09 - on 03/15/09
for 03/13/09 - on 03/15/09 (after two days)
for 03/12/09 - on 03/12/09 (right on time)
for 03/02/09 - on 03/12/09
for 03/11/09 - on 03/11/09 (right on time)
