IMAP server connection problem - blacklisted IP address
I am using iPad and iPhone mail app and this morning I could no longer retrieve emails thru my virgin router. 4G connection and webmail are both ok. Outbound smtp is ok.
message is
Server code “ALERT”, server message “Temporarily blacklisted IP Address - try again later “
The IP Address is clearly from my VM-supplied router.
I have verified using spamhaus that my IP address is indeed on their Policy Block List and that outgoing emails will still function. But I feel VM need to stop blocking me because of the PBL entry. They should surely not be referencing this for incoming emails!
Comments/explanations welcomed
thanks
This got escalated with VM security team and finally seemed to acknowledge and accept that it was blocking INCOMING messages via VM router that is the issue.
viz
“Based on your description, this appears to be related to security filtering or temporary IP-based blocks that are affecting traffic between your email client and the mail server, specifically over your VM broadband connection. This could be due to a dynamic IP being periodically flagged for suspicious behavior (even if unrelated to your use).”
They advised again to restart router, (again!), but can report that the problem has not recurred since Wednesday. 🤞
still no proper explanation as to how/why my IP address was blocked …but solution seems to be in place.
Thanks again for your help
