We are using mailman to support a 5,000 person distribution list. The
majority of our interactions with users is by email between the users and
the mailman software - humans do not get involved. The way our software is
configured, the users see the following sequence to subscribe to our email
list:
1. Web form is filled out to subscribe by user
2. Sever generates an email to the user to confirm the subscription
request
3. User replies to the subscription confirmation to the server -
typically hitting "Reply" and then "Send"
4. The user receives a "Welcome" to the mailing list email
Our users are seeing a delay of 15 minutes between step 3 and step 4 above.
Many times this delay is too much for our users to handle or confusing.
This is especially the case when the time between step 1 and step 2 above is
generally less than one minute. This delay between steps 3 and 4 many times
results in the user sending an email to our webmaster - instead of waiting
out the 15 minute delay.
That does not sound like a Mailman issue but rather a mail delivery issue
to your mail server. Is the mail server doing greylisting? That would
cause the confirmation email to initially be deferred by the receiving
mail server, then accepted the next time the sending server attempts to
send it. How long until the next attempt to send is controlled by the
sending server so I doubt they're all exactly 15 minutes.
If it's not that, you will need to look at your logs (both mailman and the
mail server) to figure out where the delay is being introduced.
