http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53632 --- Comment #1 from Frédéric Buclin LpSolit at netscape dot net 2012-06-11 11:04:57 UTC --- I did no changes to the Bugzilla code for almost two months, so I guess the problem is external to Bugzilla. Based on duplicated comments in emails, I suspect the mail server is slow these days, and so subsequent changes to bugs happen before all emails had the time to be sent. In that case, Bugzilla assumes all emails should be resent to avoid some email loss. Is there some problem with the SMTP server these days (e.g. heavy load)? This would explain it.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53632 --- Comment #3 from Jonathan Wakely redi at gcc dot gnu.org 2012-06-11 11:16:38 UTC --- Yeah :-) It's got _really_ slow. I don't remember which day it happened, but it was a very noticeable sudden change from reasonably responsive to very slow. After updating bugzilla in one browser tab/window if you hit refresh on the gcc-bugs list archive (http://gcc.gnu.org/ml/gcc-bugs/current/) in another tab/window you can see the mail from bugzilla arrive fairly quickly, but it takes much longer for the bugzilla page to finish submitting (in fact I believe it has finished submitting but is still waiting for something before reloading the next page.) I don't have access to the GCC server to see where the delay or load is, but it could be similar to the wiki-slowness described at http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53257 which is related to delays sending emails.

I could try to debug this problem, but this means I would have to spam this bug a bit to see where the slowness comes from. Is that acceptable?

So it may still be mail-related. But a SMTP server shouldn't need more than a few seconds to send only 2 emails. fche also told me that the SMTP server is doing some spam checks for outgoing emails. I wonder if that could be the reason. Still investigating...

I think we found the culprit. Either the scan must be optimized (e.g. whitelist GCC Bugzilla to not scan emails sent by it) or jobqueue must be re-enabled. In both cases, I cannot do anything myself.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53632 --- Comment #7 from Frédéric Buclin LpSolit at netscape dot net 2012-06-11 12:03:19 UTC --- fche says that some spammers create a Bugzilla account to send spam, which is why these spam checks are enabled for outgoing emails. So to mitigate the problem till jobqueue is re-enabled, one alternative could be to whitelist emails sent by @gcc.gnu.org users, as those users are trusted people. We could even extend this whitelist to all users having editbugs privs, as you need to be a trusted user to get such privileges. This way, only user accounts with no privileges would see the slowness due to these checks, including spammers. From a technical point of view, the email server should look at the X-Bugzilla-Who header, which contains the email address of the user responsible for the email to be sent. If it's a trusted user, just send the email without scanning it. This header cannot be abused by spammers.

Thanks for identifying the problem so quickly!
