Hello,

we have problems on our Plesk server that mails from amazonses taken long to get them. For 2FA this is very bad....
I whitelisted globaly @amazonses.com and also the IP spaces from them.

Any idea what to do next?

Thanks and Regards!

Whats you mail setup like? Any spam filters you are using? Any specific mail configuration? ect?

External Domain configred, mailtester shows 10/10 and all other mails coming in instant. Yes, Spam Assassin. Using SoGo as webmail client, nothing else.

This there a (significant) time difference between the first related log entry in the mail log (Tools & Settings > Log Browser > Mail) and when the email appears in you mailbox? Of does the time of the first related log entry more or less corresponds to the time if the mailbox?

For example log entry in the mail log:

2024-04-19 17:14:17

INFO

psa-pc-remote [28320]

EC90A858F31: from=<[email protected]> to=<[email protected]>

Hi, it was greylisting. I added *@amazonses.com and all IPs to the Server-wide Whitelists.

Only after adding *.amazonses.com to the White domains pattern list via cli it was working.

Thanks for your help and have a great weekend!
