I suddenly am unable to receive email sent from my friend from her primary email address and when I try to send email to that address it bounces back. Yet when we both use her alternate email address the messages are received. It's as if something is suddenly blocking access to the primary email address, Any ideas as to what might be causing this problem? Thank you.:sad:

This expands on observations from , , and with a short, evidence-first troubleshooting checklist that separates two different failure modes seen in this thread: (A) SMTP-level delivery rejections (the “bounce” case) and (B) TLS/certificate trust errors when accessing webmail or using an SSL/TLS-enabled client.

Start by collecting the failure evidence. The single most useful items are the full bounce notification and the raw message headers. Look in the bounce for a numeric SMTP reply (for example 550 or 5.1.1 vs 4xx) and any diagnostic text. A typical useful header excerpt looks like this:

Diagnostic-Code: smtp; 550 5.1.1 <user@domain.com>: Recipient address rejected: User unknown
Received-SPF: fail (domain of sender.com does not designate 198.51.100.23 as permitted sender)
Authentication-Results: dkim=none; dmarc=reject header.from=sender.com

Interpreting that: 5xx SMTP codes are permanent rejections (user unknown, blocked, or policy reject). “Received‑SPF: fail” or “dmarc=reject” points to sender authentication/policy (SPF/DKIM/DMARC) causing the bounce. If the code is 4xx the failure may be transient and will usually retry.

For the certificate/TLS warnings mentioned by , check these in order: view the certificate details (issuer, CN/subject, expiry dates), confirm the client/device clock is correct, test from a different device/network, and temporarily disable local HTTPS/SSL inspection in anti‑virus/firewall software to see if that removes the warning. Ensure the mail client is connecting to the host name that matches the certificate (IMAPs 993, POP3s 995, SMTP submission 587 with STARTTLS or SMTPS 465).

Practical next steps and escalation: send test mail from a different provider to confirm whether rejection is global; have the sender check account status and any provider notifications; verify MX records and whether the sending IP is on public RBLs; correct SPF/DKIM if the bounce cites them; and, when contacting either provider, include the full bounce text and raw headers and the exact times. Do not accept or bypass an untrusted certificate without verifying the cause.

Make sure here primary email address is not suspended. Especially if you're dealing with the n00bs on the hotmail staff they block accounts who dont use their service in 6 months time periods.

Also make sure your emails aren't going to her spam bin. That could (or possibly could not) be a major issue.

your hypothetical does not cover my problem.
my problem is that when trying to receive email i get the message that the web site has a problem with a security certificate and recommends i sign off so i can't send email either.

I think its problem with her primary email Address. Are you sure the primary email id of her is in working status.

The email bounces back only if recipients email ID doesn't work.
