Thanks much for handling it the way you are now, it at least helps in
getting all mails instead of missing.

The last time even before Florian reported the issue, i was seeing it,
but initially thought it was a problem related to my account, tried
unsubscribe & subscribe, contacting list owner etc, none did help,
only upon seeing Florian's mail, did realize that it was a generic
GMAIL issue.

Don't know whether you had done some changes, now able to get mails in
realtime. Next time upon seeing this kind of issue will request GMAIL,
irrespective of the outcome, i will do my part.

And thanks for taking the time to reply.
