Amazon AWS Email Amazon SES Issues

Amazon SES was working great for 9 days. Came home today to a huge email error log and my daily digest for my forum kicking out all kinds of errors. 9 pages of email errors / not sent emails. Keep getting a 421 error on test sends... some send, some get the error.

---

Had to switch over to reliable Mailgun. More expensive, but always works.

 

I already increased the rate limit, I'm at like 14 emails a second.

 

I'm wondering if OVH is blocking port 587? I have the FW in permanent mode. I put it in auto mode to see if that makes a difference. Otherwise, I can switch to port 2525 which mailgun uses as an alt to 587.

 

Yea, for 9 days. Today all of a sudden I got a 10 page email error log and a cron error on the digest task.

 

Not bad at all.

 

Put in the request to Amazon. They gave me the same level as you. So, I'm going to switch back over and see if Amazon works again.

Things seem to be working good now that I moved to Mailgun and am using their alt TLS port of 2525.

Do you by change know how to setup a rule in the OVH firewall not to block outgoing on port 587? Since I keep the server in permanent mode, OVH firewall could be blocking that port since I send out a lot of emails at once. Some threads have 200+ subscribers.

 

I believe if you use established that's for outbound.

I thought you used OVH firewall. I'll have to research how to set that up. Thought you might've known.

OVH support. LOL! You're funny.

 

Things seem to have calmed down. Not getting anymore errors now that I have the Firewall on auto and using Mailgun on port 2525. Might switch back to SES to see how that goes. Mailgun is pricey @ $30 a month for me for 1 website.

 

Sparkpost is horrible. Great to start then they ban you. Been there, done that.

Amazon is great. I get an email every time there is a delivery problem. I can then force that user to update his email address via a plugin.
