My team has a script on a cronjob schedule that checks for the presence of certain files in a directory, and if they are there, includes them in a report that is sent daily to our team's emails.
However, most days that report is empty, which is redundant and clutters my inbox. I suggested to my team to modify the script to only send out the report as an alert if there is at least one of these files. But they explained that if the script encounters some error, we won't know because the emails aren't sending - a false negative. A daily email report hence eliminates this concern.
I still don't think this is scaleable - e.g., if there are 10 independent alert systems this would make for a messy inbox. What is the best way to implement a more robust version of my approach - to send an alert only if a criterion is met - without the threat of false negatives?

This Odoo company we're working with basically sends a lot of e-mail. One e-mail thread can turn into 100+ e-mails with different people brought into the conversation (CC'd) at different times. Due to the complexity of their e-mail management, they want to use their Gmail interface (Google Hosted) and CC an e-mail into odoo and they want it to get tracked in a thread. I've basically already done that... they have an e-mail like odoo+res.partner-432#domain.com (although it's hashed to not be easily readable) - they CC this and the full body thread gets included in chatter (mail.message) under respective model / id.
The challenge with this: the chatter messages can get huge very fast, due to their e-mail messages (because each e-mail includes main reply, and all previous history on thread). I've looked into some systems that have a "reply above this line" - and it just takes the latest message. And in those systems, eg. ticketing systems such as Zendesk, help scout, I believe the teams are using the ticketing system (not a gmail) and thus there is much more control over the inbox and incoming email (not to mention, those e-mails are usually 1-to-1, not including groups).
My questions:
Is there any other workaround that you see here to have odoo pull in only the last e-mail reply and not the full e-mail thread? I could probably build something like this: https://github.com/zapier/email-reply-parser - and hook it into odoos e-mail parsing, but that works on text format e-mails only (not HTML)... only. So it's not bulletproof, and I'm not sure it's worth it.
Even if this client DID use odoo 100%, I still don't think it would be possible to get it to work the way they want without major customizations (eg. Odoo's default behavior is to include all past e-mail threads)
I'm curious if anyone here see's any other solutions, otherwise – I doubt there is something here I haven't seen. :) (But very open to be proven incorrect!)
Currently I am working with getting rid of voicemail to email files to save space in our archiving solution. Currently I have a search-mailbox script written to take care of deleting the voicemail e-mails. Is there any other solution out there that would be more effective in controlling the deletion of specific attachments from users mailboxes? The script works but it seems crude and very ancient to me after I finished writing it. I also looked at Transport Rules and Retention Tags but neither seem to give me much granular control over just attachments or just a specific attachment name. Is there an Industry Standard on handling a situation similar to mine or am I headed in the right direction with just PowerShell?
I need to write a windows service to send emails. The emails will likely be stored in a database table and they should be sent as early as convenient. It would be advantages to have multiple threads sending messages as there will be hurts at certain times of the day however it is not good to send the same message multiple times.
So I'm having a little bit of trouble understanding in this kind of scenario how I can best leverage quartz.net to alleviate some of queueing and concurrency issues. So my architecture questions are:
1. For this kind of scenario, is it best for a Job to check if there are emails to send or should a job be to actually send one email?
2. If the answer to 1) is to check for emails to be sent then that would leave me with a concurrency issue and I would need to use DisallowConcurrentExecution which would result in only 1 email being sent at a time?
3. If there answer to 1) is send a single email then I take it the job details would need to reflect the specific ID of the email to be sent?
4. In either case - two web users could trigger the creation of the same email job (concurrently). So it doesn't seem that Quartz really helps solve my problem - it might provide a nice architecture for a unit of work and controlling polling frequency but not really the core of my problem? Or am I mssing / over thinking something?
Finally, just to be clear, each email relates to a specific Order so there is ID and state potential. So because two web users can send the same email at the same instant in time should not result in two emails being sent.
Look forward to any advice.
Thanks

Quartz.Net would meet your scheduling needs.
However, you have conflicting needs. You want "more than one thread" to send the emails, but you also want "Do not want duplicate emails".
The DisallowConcurrentExecution will prevent multiple instances of the same job running at the same time. However, if you have only one instance of the job running, you don't know which individuals emails have been sent or not sent.
If you only keep "these emails have been sent, and these haven't" in memory.....you're always at risk of sending duplicates.
You can solve this, but you're gonna have to have a "pessimistic" flag on which emails have already been sent. Like at the database level.
So if you want multiple threads to send emails...that's ok. But your "get some emails to send" code is going to have to 'mark' the emails it is working on. (So the next thread doesn't get them). Then you have to mark them again right after they are sent.
Quartz is good for scheduling the "when" your jobs run. But it doesn't have the ability to "track" which emails you need to send and which ones have already been sent. That's gonna be your responsibility.
I had this similar problem....where I had many many users trying to "get at" a bunch of to-do items. Thus why I wrote this blog entry for Sql Server. I needed to "mark" the rows, but also had to order them before I marked them.
http://granadacoder.wordpress.com/2009/07/06/update-top-n-order-by-example/
I also added some "hints".......
WITH ( UPDLOCK, READPAST , ROWLOCK ) –<<Optional Hints
because so many different users were trying to "get-at" the items.
(Think about how T1cket M#ster has to work.......there has to be some pessimistic locking on the tickets....and they have a timer that releases the locks if you don't buy the tickets in time).
Hope that helps.
Due to high network traffic during the day, many of our Jenkins builds must run in evenings and during the night. Emails are sent containing reports, notifications of broken builds, etc. However, I don't want the emails to be sent to developers in evenings and during the night. Is it possible to queue all the emails and send them e.g. between 8-17 office hours? So if a build breaks during the night, an email is sent at 8am.
Unfortunately, as far as I know, there is no plugin that allows to delay email sending. However, maybe you can give a try to the script capability of the email-ext plugin. It allows you to use JS or Groovy scripts in the template. In such script, you may write a loop that "waits" 8am to send the email.
But personnally, I don't like that idea, it's not really a good way to achieve that, and in addition it will certainly make the final result of the build wait until 8am (the build will only finish once the mail is effectively sent). This will also have the drawback that the job will take one place in the Jenkins job queue, potentially blocking another job...
Maybe developing your own plugin (by forking mail-ext plugin for example) would be a better idea...
Let me spread my ideas.
I'm also not aware of any existing functionality to achieve that via Jenkins.
Plugin would be probably the best way (possibly beneficial for others is published to public).
The alternative solution coming to my mind is in case you are in a situation, where you have control of the e-mail server, that might also be place to achieve your goal.
As for the SMTP (based on the sever you use) there might be a solution.
Possibly solution provided here (sendmail in queue-only mode) could help you:
How can I delay mail delivery through an SMTP relay, possibly sendmail
Does anyone know a good tool to test whether your emails are going into spam folders?
My web app generates emails to users, and I've been getting a lot of reports back from people saying "hey, no one ever responded to my message".
I have SPF rules in place and functioning correctly (email header shows an spf pass). I've also run my message through spam assassin and it scores very low.
Any other ideas?
To know if your email goes in the inbox, you need to get a metric called "Inbox Placement Rate". This indicator can be provided by Return Path, but it's quite expensive. If you're not sending huge volumes it might not worth it. The only way to measure the IPR is actually to have a certain number of test inboxes... In other words: the only way to chech that your email is not in the spam folder is to make the test and see what happen. There is not other magic solution and that's what Return Path is doing.
This means that when you hear about people claiming they have a 99% deliverability / delivery, it might be true be it just means that the email was "accepted" or "delivered" by the ISP. It's a lot, but it's not everything!
What you should do is the following: use an ESP focusing on deliverability. Personally I work for Mailjet. I believe it's the best value you can get: personalized DKIM and SPF are provided for free, you get the antispam scorings, the analytics, Ip reputation monitoring, throttling, etc. It's an all in one tool to avoid the headaches of optimizing yourself. It's more expensive that Amazon SES because you get a lot of added value services, but it has much lower prices than a lot of traditional ESPs!
Bottom line is: optimizing everything yourself is a full time job. Knowing exactly if an email is in the inbox or not will cost you a lot. The best way to proceed is to:
respect the best practices (opt in, not too much images, no red, etc.)
get some metrics such as open rates, click rates, delivery, etc. and watch their evolution over time. Any change from one sending to the other might be a signal for a problem you want to investigate.
Use a tool that takes care all the deliverability optimizations
Mailjet is cool because no matter which plan you pick, you get to use all the options. But if you want a full overview of what is existing, check out this comparison table:

If you're a perfectionist who wants to finetune the layout, how the emails are displayed etc. Check out Litmus, it's also a quite powerful tool!
http://litmus.com/
Simple answer: Use Mailgun!!!!
http://mailgun.net/
They will do all of your email deliverability and setup for you and give you a powerful API to build on! They are amazing. You'll never have to worry about domain keys or SPAM filtering again!
You should also check that your IP is not on any of major blacklists. dnsbl.info
This will at least give you an idea if you actually are getting flagged as spam.
For the past two years, we've used the service DeliveryMonitor.com. However, they've stopped accepting new applications which is a big red flag...
I'm currently evaluating the service from emailreach.com using their free trial
... We are now using DeliveryWatch.com with pertty good results thus far...
