trac can fail to email the reporter

[tct]

These trac tickets did not email to me on replies:
​https://community.openvpn.net/openvpn/ticket/1217
​https://community.openvpn.net/openvpn/ticket/1164

Please add a simple reply to this ticket for my test.
Don't modify cc etc.

Test

[tct]

Test failed.

I received the initial post notification:
<0100016ecd36f2ca-11cadf8a-2867-466a-a9d4-69476185afae-000000@email.amazonses.com>

Full message header available on request.

But no notification of replies.

Checked gmail spam folder: no spam.
Checked gmail other folders: no notification.

I will receive notification of my own reply.

[tct]

Notification of my reply received.

Note: Not threaded.

[tct]

Oddly enough, my reply to my reply was indeed threaded correctly.

Moo

Replying to Gert Döring:

Moo

received !

Did you find a notification email moo for my comment on your ticket ?

[tct]

Sometimes things go wrong ..

So that people understand what is going on here:

If you fill out a ticket like #1229, where the reporter has only used the description field to describe the issue, then the reporter will not receive any reply email notifications.

If the reporter fills out a ticket like this one #1238 and adds a subsequent comment then the reporter will receive email notifications.

So, by default the reporter is not subscribed to the ticket unless/until they add a comment.

This does not seem to be conducive to how trac ought to work.

[Samuli Seppänen]

I'll check if there is a setting to fix this.

[Eric Crist]

This might be related to the IPv6 PTR records and Gmail blocking those messages, @mattock.

[Gert Döring]

Don't send mail to gmail over IPv6. This is a world of needless extra hurdles.

I received this message after creating ticket #1351

Warning: The ticket has been created, but an error occurred while sending notifications: (454, 'Throttling failure: Maximum SigV2 SMTP sending rate exceeded.')
