  @Gigini 

Hi, Thanks for the feedback.

Can you give some examples of the email servers?

 

Are you able to connect the laptop directly to the ISP modem/router, bypassing Deco to see whether you can receive any emails from the mentioned email servers?

 

Here are some suggestions for your reference:

1. Enable "UPNP" under Deco APP>More>Advanced>NAT Forwarding.

2. Change the IPV4 DNS to 8.8.8.8/8.8.4.4: How to change DNS server settings on my Deco

 

By the way, since it worked well before also works occasionally now, have you made any adjustments to the email settings recently, like any firewall settings?

Best regards.

Thx David for the quick response.

email server is from my Internet Service provider "telenet.be"

using IMAP & port 993 (incoming) ---> gives problems

smtp & port 993 (outgoing) seems to work

all other emails (e.g. gmail - icloud) are working fine.

 

Direct connected with ISP modem...no problems

UPNP was already enabled

changing DNS to 8.8.8.8/8.8.4.4 doesn't help

 

It looks like a problem with the ISP (also @ISP problem posted), but why doesn't it work after/with the deco for several users and it seems to work always outside the deco network.
