Here&#8217;s how to fix it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Correct Veerhost Email Settings<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Use these settings in your email client:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Setting<\/th><th>Value<\/th><\/tr><\/thead><tbody><tr><td><strong>Incoming (IMAP)<\/strong><\/td><td>mail.yourdomain.com \u2014 Port 993 \u2014 SSL\/TLS<\/td><\/tr><tr><td><strong>Incoming (POP3)<\/strong><\/td><td>mail.yourdomain.com \u2014 Port 995 \u2014 SSL\/TLS<\/td><\/tr><tr><td><strong>Outgoing (SMTP)<\/strong><\/td><td>mail.yourdomain.com \u2014 Port 465 \u2014 SSL\/TLS<\/td><\/tr><tr><td><strong>Outgoing (SMTP alt)<\/strong><\/td><td>mail.yourdomain.com \u2014 Port 587 \u2014 STARTTLS<\/td><\/tr><tr><td><strong>Username<\/strong><\/td><td>Your full email address (e.g. info@yourdomain.com)<\/td><\/tr><tr><td><strong>Password<\/strong><\/td><td>Your email account password set in cPanel<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Replace <code>mail.yourdomain.com<\/code> with your actual domain. If your domain isn&#8217;t pointed to Veerhost yet, use your <strong>server hostname<\/strong> instead (found in cPanel \u2192 Server Information).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Fix 1: Port 25 Is Blocked (Can&#8217;t Send)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Port 25 is blocked on most shared hosting and ISPs to prevent spam. <strong>Never use port 25.<\/strong> Use port <strong>465<\/strong> (SSL) or <strong>587<\/strong> (STARTTLS) for outgoing mail instead.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Fix 2: Authentication Error<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If you see &#8220;Authentication failed&#8221; or &#8220;Wrong username\/password&#8221;:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Confirm the password by logging into <strong>cPanel \u2192 Email Accounts<\/strong> \u2192 click <strong>Check Email<\/strong> next to your address \u2014 if that works, your password is correct<\/li><li>Make sure your <strong>username is the full email address<\/strong>, not just the part before @<\/li><li>Reset the email password in <strong>cPanel \u2192 Email Accounts \u2192 Manage<\/strong> if needed<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Fix 3: SSL Certificate Warning<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If you get an SSL certificate warning, it&#8217;s because <code>mail.yourdomain.com<\/code> may not have a matching SSL cert yet. As a workaround, use your <strong>server hostname<\/strong> as the mail server address instead. Find it in <strong>cPanel \u2192 Server Information<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Fix 4: Emails Received But Not Showing<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If you&#8217;re using <strong>POP3<\/strong>, emails are downloaded and deleted from the server. Switch to <strong>IMAP<\/strong> so emails stay synced across all your devices and remain on the server.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Still Not Working?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Contact Veerhost support at <a href=\"https:\/\/veerhost.com\/de\/support\/\">veerhost.com\/support<\/a> and include the exact error message your email client shows.<\/p>","protected":false},"excerpt":{"rendered":"<p>If you can log into webmail but can&#8217;t send or receive emails via an email client (Outlook, Thunderbird, Apple Mail, etc.), the [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":1930,"menu_order":7,"comment_status":"open","ping_status":"closed","template":"","doc_tag":[],"class_list":["post-2303","docs","type-docs","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/veerhost.com\/de\/wp-json\/wp\/v2\/docs\/2303","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/veerhost.com\/de\/wp-json\/wp\/v2\/docs"}],"about":[{"href":"https:\/\/veerhost.com\/de\/wp-json\/wp\/v2\/types\/docs"}],"author":[{"embeddable":true,"href":"https:\/\/veerhost.com\/de\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/veerhost.com\/de\/wp-json\/wp\/v2\/comments?post=2303"}],"version-history":[{"count":1,"href":"https:\/\/veerhost.com\/de\/wp-json\/wp\/v2\/docs\/2303\/revisions"}],"predecessor-version":[{"id":2310,"href":"https:\/\/veerhost.com\/de\/wp-json\/wp\/v2\/docs\/2303\/revisions\/2310"}],"up":[{"embeddable":true,"href":"https:\/\/veerhost.com\/de\/wp-json\/wp\/v2\/docs\/1930"}],"wp:attachment":[{"href":"https:\/\/veerhost.com\/de\/wp-json\/wp\/v2\/media?parent=2303"}],"wp:term":[{"taxonomy":"doc_tag","embeddable":true,"href":"https:\/\/veerhost.com\/de\/wp-json\/wp\/v2\/doc_tag?post=2303"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
