I'm getting bounce when I send an email to a specific address

I'm getting bounce when I send an email to a specific address using SES, from gmail the mail is delivered correctly

For Transient -> General AWS says The recipient's email provider sent a general bounce message. You might be able to send a message to the same recipient in the future if the issue that caused the message to bounce is resolved. How can I fix the issue if I do not know the problem?

"eventType":"Bounce",
"bounce":{
"bounceType":"Transient",
"bounceSubType":"General",
"bouncedRecipients":[
{
"emailAddress":"{some_email}",
"action":"failed",

}

Solution

  • Not much you can do, seems like the recipient side is checking IP reputation and found that SES IP (sending IP) 54.240.8.90 is in the blacklist, it also sent you a bounce back with custom message "smtp; 535 5.7.8 Error: blocked by Block Address check from 54.240.8.90".

    Seems like they're using SORBS SPAM .

    Couple of things you can try:

    1. Remove the IP from SORBS by yourself (it may get added again)

    2. Contact AWS to contact them to remove it from Blacklist.

    3. Try dedicated IP pool.
