SMTP Roundtrip



Do you have any suggestions for the SMTP Server outside? I have tried: gmx. It stopped after 40 messages outlook.com stopped after 1 hour gmail worked for one week. Now I get the message: Daily sending quota exceeded. I test all 4 minutes

The suggestion smtp.web.de I found in another post, doesnt exist anymore.

Hey t_ore,

why do you have an test interval of 4 minutes? Maybe it is useful to use an lower but continuously interval. Witch such an high test interval you would be listed on a blacklist in a couple of weeks, if they don't block you. Mail-Tests are very critically.

As an example, you can use 10 min as interval and gmail as service with (smtp.gmail.com) as mail relay. Don't forget to add your user credentials and the HELO-Ident. In one of my tests it worked for the last 5 month without a problem, especially it's a real one ;).

So a tip from my opinion, don't test as often as you can. This isn't the best way.

Maybe this is what you wan't
