MT4 Email Server Failure

Hi, I've been working with email to sms alerts in my EA using the SendMail function. I currently have my email set up through GMX which forwards all incoming messages from MT4 to my cell phone. This all works great about 90% of the time. The other 10% of the time I get delivery delays from my email server or out right message failure from mt4. I send anywhere from 50 - 200 alerts within a 24 hour period which might be part of the problem. Today for example the email alert system worked fine for about 16 hours. I would receive texts alert within about 30 seconds of them sending off from MT4. This gap started to widen and eventually I was getting a 30 minute delay in messages. Eventually MT4 started giving me an error "Mail: 550 Sender address is not allowed" every time I tried to send out.

I've tried setting up through a couple different email servers, and have also tried sending the messages directly to my phone from mt4 instead of using the email forwarding. No matter which way I configure this I always seem to get inconstant results. I think what might be happening is that I am exceeding a hourly or daily "quota" for outgoing messages and am getting tagged as a spammer which causes longer delays in messages as the day goes on. This in turn is causing MT4 to back up pending messages and eventually fail. I know that MT4 has it's own quota for pending messages before it fails and needs to be restarted.

Basically I have a couple different questions and I would be interested in any additional info anyone could provide.
1. Am I right about what is causing this error? Anyone have any other ideas as to what could be causing my problems?
2. Is SendMail the most reliable way to send outgoing messages from an EA? Is there maybe some alternatives I could look into?

Thanks in advance for any input.

Bourne-
Have you tried restating the platform? See if that clears it up.
Have had something similar while testing indicator or EA and there is a limit with MT4 but its easily cleared up by restarting the platform. Don't know if the same is true for Live trading.

Restarting will fix the problems with MT4 backing up, but it doesn't seem to do anything for the server side of things. Usually I have a couple EA's running and if there are any active trades opened up it's really inconvenient to shut everything down in the middle of trading.

I actually opened up a separate version of MT4 that has a demo server set up and tried sending mail through it with the same settings. It didn't have any problem with the exact same settings. This is after I restarted my "problem platform" which had been sending everything just fine for almost 16 hours up to that point.

I've attached the two screenshots of the platform that had the error and the one that didn't. It started working again after I restarted it a couple times.

Also I believe the "550 error" is specific to GMX. It's the first time I've seen that specific error, but I have re-created this same problem across three different email providers.

Do you experience the same problems using your local ISP/Cable Provider email?

You should check in the terms of service for any quotas. I seem to recall a limit of 10 per hour and 100 per for one provider. My memory is kind of vague because that was a few years ago. No provider will give you unlimited quota unless you pay big money and are reputable.

SendMail() is about the worst way to send email alerts, but it simple and easy to implement. I have seen similar delays and missed alerts which were likely caused by MT4. As well , sending attachments and CC are impossible.

Ther are alternatives which are technically challenging but provide instanteous delivery and 100% reliability. Presumably you only want to send to yourself. I would recommend setting up a SMTP server and routing emails through that.

I haven't tried that. I would have to call my ISP and get all that info. Might be worth trying out.

I set up hmailserver a couple weeks ago and messed around with it, but I just configured it with the gmail server. I ran into more of the same problems. I assume you are talking about setting up a localhost. Wouldn't you still be using SendMail() with this method?

Didn't you have email services included when you signed up for the service?
My provider is Cox. I've never used anything else and have had no problems. I just checked a day where I was testing an indicator in addition to my other Alerts and there were a total of 429 in one day, over 350 from the 1 indicator that was sending too many alerts but nevertheless my service provider handled it no problem.

I think it was included in our internet bundle I just never have needed it or bothered to use it.

The goal is to avoid using SendMail() by using a custom library in a DLL. Don't know hmailserver. I tried JangoMail and a few others I can't recall.

Ok. I'll need to look into and read up on creating a dll for mt4. My knowledge on the subject is pretty basic. Is that the preferred alternative to using SendMail()?

There are several alternatives, but the others are more challeging ( more features). You might want to look at some third party MT4 signal software. Some are free, but most cost. If you have a mission critical requirement for alerts, don't use SendMail().

Most people only need a few signals a day and if some are missed, its not a big deal. SendMail() is fine for them.

EDIT: here is one the options I mentioned above

Hi Guys,

I encountered issues with GMX email sending and upon researching the problem I found out there is a 26 email limit. Any work-around/solution to this?

SOLUTION:

Can't comment on the email limit thingy but the common "failed" error can be fixed like this:

If people ever ask how to make mt4's email alerts work these days, for example with the proposed gmx.com free email server they can log into gmx.com Settings to enable "Send and receive emails via external program" and click Save button.
