mhermann Posted February 25, 2020 Share Posted February 25, 2020 Hi. I am using WHMCS in SMTP-sending mode. The e-mails to our customers are always ending up in the spam folders of major providers. What is interesting: If I send an email using an Outlook-client through our mailserver it gets delivered correctly as ham to outlook.com/hotmail. I started investigating... Reverse PTR correct, SPF correct, but than I ran a header analyses on mxtoolbox.com and found that whmcs is somehow changing the HELO ( smtp.mailfrom=info@mydomain.de smtp.helo=www.mydomain.de). The mailserver is usually using mail.mydomain.de Any ideas how to fix that? It is very anoying to not being able to deliver emails correctly. 0 Quote Link to comment Share on other sites More sharing options...
TheHostingHeroes Posted February 26, 2020 Share Posted February 26, 2020 try using SMTP with SMTP authentication and see if it helps in your WHMCS config. 0 Quote Link to comment Share on other sites More sharing options...
mhermann Posted February 29, 2020 Author Share Posted February 29, 2020 I am using username/password with smtp. However there is no extra button to configure SMTP auth or am I missing something? 0 Quote Link to comment Share on other sites More sharing options...
WHMCS ChrisD Posted February 29, 2020 Share Posted February 29, 2020 @mhermann thanks for your post, in Setup > General Settings > Mail you should be able to enter your SMTP Server, username, password and choose SSL, TLS or None as the security. Can you confirm are which platform you are using to send emails? 0 Quote Link to comment Share on other sites More sharing options...
mhermann Posted March 1, 2020 Author Share Posted March 1, 2020 Everything is setup as you suggested. I also checked the mail.log and it is showing a correct sasl-auth. 0 Quote Link to comment Share on other sites More sharing options...
WHMCS ChrisD Posted March 1, 2020 Share Posted March 1, 2020 @mhermann are you using a third party app to send emails like gMail or Office365 or just a standard mail server? Have you checked your domain on a tool like MXToolbox to see if your domain is blacklisted? 0 Quote Link to comment Share on other sites More sharing options...
mhermann Posted March 2, 2020 Author Share Posted March 2, 2020 Hi. No we are using regular postfix on the same host sending several thounsand mails each day which don't end up in spam-folders. MX-Toolbox shows no errors for the domain and the mailserver. 0 Quote Link to comment Share on other sites More sharing options...
BigGainz Posted March 10, 2020 Share Posted March 10, 2020 I am following along with this also. 5 emails are sent in total when someone purchases from me. Everyone receives the first 4, the 5th one either ends up in everyones spam folder or just totally blocked by the email provider. Of course it is the most important one that contains their username and password. I cant seem to figure out how to make it look any less spammy. 0 Quote Link to comment Share on other sites More sharing options...

david891 Posted April 17, 2020 Share Posted April 17, 2020 Hello, I am having a similar issue, emails for "client sign up" "account information" and "email address validation" are spamming. I have all records set up and spam assisn says not spam. I am also using SMTP and a dedicated IP. Any suggestions? Regards, David 0 Quote Link to comment Share on other sites More sharing options...
mhermann Posted April 18, 2020 Author Share Posted April 18, 2020 (edited) Hi David, when I send the same e-mail, same adresse, same IP, same content from outlook instead of WHMCS it works. It must be a WHMCS problem. I ended up signing up for the AWS Mail Gateway. It's free up to a certain amount and somehow that is working. I don't know if Amazon is changing the mail headers or just has a much better reputation. However. Result: It is working now. Another anoying WHMCS-situation ended (without the help of WHMCS - of course 😉 ) Edited April 18, 2020 by mhermann 0 Quote Link to comment Share on other sites More sharing options...
wsa Posted April 18, 2020 Share Posted April 18, 2020 (edited) This is going on a long time I get also when my clients use like Gmail, Yahoo or outlook it go to spam.

I need to kept telling my clients to check the spa,/junk folder I do believe gmail, outlook do it intentionally send email to junk, because they want us to assign to their package G-suite and office 365 email. It is really frustrating offer email accounts with hosting because customer can not have a reliable email service. First I was thinking my email goes to junk because I do not have a dedicated server yet, but VPS...Now I see guys say even on dedicated emails go to spam...I can only imagine that Gmail and outlook do it intentionally. Hope you find a better email configuration guys and share it on the community. In my case, after I assign to g suite email, now all my emails goes directly to customer inbox. But I am afraid to sell hosting saying to customer that they can have a company\professional email, if emails goes all to junk 😓 Edited April 18, 2020 by zitu4life 0 Quote Link to comment Share on other sites More sharing options...
mhermann Posted April 18, 2020 Author Share Posted April 18, 2020 @zitu4life You are talking about a different problem. In your case: Every email from your network goes to spam folders. In my case and as I believe in davids case only WHMCS mails go to spam-folders. Every other email from my network is going into inboxes as expected. 0 Quote Link to comment Share on other sites More sharing options...
BigGainz Posted April 19, 2020 Share Posted April 19, 2020 Just like my issue also. Customers get a total of 5 emails throught out the purchasing process. 4 go too their inbox, the last and most important one is the one that goes to junk/spam 0 Quote Link to comment Share on other sites More sharing options...

In that case, I would think the way WHMCS deal with reader emails, could be one of issue, but not sure. 0 Quote Link to comment Share on other sites More sharing options...
AlexMartin Posted January 13, 2021 Share Posted January 13, 2021 Hello. Did you guys got the issue resolved ? I didn't get this issue, we configured our mails over gsuit. Now I can see normally our all mails landing in inbox but in case of whmcs auto generated mails all of them landing in Spam folder. We checked with rediffmail and in this case it goes to Inbox. I guess it's the issue with whmcs and gmail. Can anybody help us how to proceed, our IP reputation, blacklists, DKIM, SPF records and PTR records are all ok as of now. 0 Quote Link to comment Share on other sites More sharing options...
AJX Posted April 6, 2021 Share Posted April 6, 2021 Hi all, We have the same problem, and gmail spams our emails while our IP is not in a blacklist and our reverse DNS, SPF, DKIM and DMARC our OK. Do you know how we should resolve this problem? 0 Quote Link to comment Share on other sites More sharing options...
sol2010 Posted October 2, 2023 Share Posted October 2, 2023 (edited) Just started getting this issue with Gmail. Sending through WHMCS SMTP to cpanel server then out to clients. Have correct PTR, DKIM, SPF and DMARC all set up good via cloudflare and have checked blacklists - all clean - but Gmail says "lots of emails from domain.com are identified as spam". We are not spamming anyone, only sending out invoices and support replies. Some customers are not paying invoices citing "never received the invoice" Edited October 2, 2023 by sol2010 0 Quote Link to comment Share on other sites More sharing options...

CMS911 Posted May 13, 2024 Share Posted May 13, 2024 I have SMTP enabled and I have SPF, DMARC and DKIM all setup. However, WHMCS seems to be modifying the DKIM signature after sending the email. 0 Quote Link to comment Share on other sites More sharing options...
monsterit Posted May 15, 2024 Share Posted May 15, 2024 I would look through the Dkim and see what might be causing this. Is your server running an AV/clammail? which can then distort the dkim. 0 Quote Link to comment Share on other sites More sharing options...
