The lines in red are quotes from your earlier posts
The lines in blue are from Spamhaus' explanatory notes https://www.spamhaus.org/zen/ and https://www.spamhaus.org/pbl/
Apologies in advance for the length of this post but just to try and hopefully clarify a few things:
"it seems my IP address has been blocked by Spamhaus ZEN"
Here's what Spamhaus say on the ZEN blocklist:
"ZEN is the combination of all Spamhaus IP-based DNSBLs into one single powerful and comprehensive blocklist to make querying faster and simpler. It contains the SBL, SBLCSS, XBL and PBL blocklists"
"Hello, seems to be listed on PBL."
So if your IP address is not on the SBL, CSS, XBL blocklists it is only on Spamhaus ZEN because of the PBL entry.
"The Spamhaus PBL is a DNSBL database of end-user IP address ranges which should not be delivering unauthenticated SMTP email to any Internet mail server except those provided for specifically by an ISP for that customer’s use."
So as @用心棒 has already said, If your email client is set to use your authentication credential to sign into the mail server then being on PBL will not affect your ability to send emails.
In fact Spamhaus also give this advice to Internet Service Providers on how to use the ZEN blocklist:
"Because ZEN includes the XBL and PBL lists, do not use ZEN on smarthosts or SMTP AUTH outbound servers for your own customers (or you risk blocking your own customers)."
"i'm still receiving send/receive errors when connected to my wifi"
So bearing all that in mind, if you are currently seeing any email issues check your IP address on Spamhaus' own search page https://check.spamhaus.org/
If you are only seeing your IP address listed on the PBL it seems something-else other than IP blocking is going on here.
To troubleshoot that further I would suggest using the curl command to see what error the VM SMTP server is reporting:
1) Copy the following line of command text and then paste it into a MS Word document (or which ever text editor you prefer) so that you can edit it.
curl -v smtps://smtp.virginmedia.com -u username:password
2) Once you have pasted it into Word, replace username with your full Virgin Media email address, and password with your email password. So that part should now say something like richardbranson@virginmedia.com:sdfxyz1234 It is important to keep the colon : and the space before and after that piece of text exactly as per the original line of text in step 1.
3) Type cmd into the Windows 10 / 11search bar, press Enter and then Open the Command Prompt app.
4) Copy the full line of text that you just amended in step 2 from the Word document and paste it where the curser is blinking in the Command Prompt. Then press Enter.
After a second or two you should then see a string of output that possibly ends with a line which says something like
< 535 5.7.8 Authentication Credentials Invalid (VM300)
It is that line, particularly the VMxxx code that we need you to give us please. (Do not post the full output from the curl command.)
Sorry to go on at such length but that VMXXX error code would be very useful. to know where to go from here.
