[@AmwaajPresales]

Hi I completed all the steps. The only thing I couldn't add was the TLSA record because Hostinger (Hpanel) does not have that option. Although mailcow shows that entry in not required. The emails are not going through. What would you advise?

[@FluxxSet]

@@AmwaajPresales tlsa is optional

[@FluxxSet]

@@AmwaajPresales it should send mails

[@FluxxSet]

@@AmwaajPresales on histinger records updates takes time , so may be in your case records are not updated yet

[@AmwaajPresales]

@@FluxxSet okay bro I will take your advise and wait for upto 24 hours. If it doesn't then I will report back to this comment thread.

[@FluxxSet]

@@AmwaajPresales okay , if that doesn't fix message me on telegram we will have a meeting, I'll look into issue.

[@leedao_official]

Can you show how to disable Selfsign SSL and use SSL provided by the Sectigo Certificate Authority. Tks!

[@FluxxSet]

it will only generate Selfsign ssl in case lets encrypt fails to get ssl .

[@FluxxSet]

and this also can happen in case 1 - if request quota is over 2 - dns record issue

[@leedao_official]

@@FluxxSet do you think Self-sign SSL is just for testing and should not apply for Production environment? I'm just wonder Google & Microsoft accept Self-sign SSL or not.

[@FluxxSet]

@@leedao_official it's only for testing

[@er.jitu4]

I want to setup this on my azure linux(Ubuntu LTS) vm and its running on port 22 ,so is it necessary to have port 25 on it? Please tell me, thanks

[@FluxxSet]

The Azure platform blocks outbound SMTP connections on TCP port 25 for deployed VMs. so bcoz of this you can not host mail server on it .

[@FluxxSet]

you should try Digital ocean or contabo

[@er.jitu4]

@@FluxxSet and what if I allow all outbound/inbound port rule from the SMTP service 🤔

[@FluxxSet]

its not up to you , its blocked from Azure , but if request to Unblock and if they allow then , it will work

[@mohfaisal9070]

@@mohfaisal9070 check if you can disable ipv6 while creating, edit docker compose file and check how you can disable ipv6 may be removing the ipv6 entries will help . Let me know that fix else I'll check myself in compose file

Lie bro digital ocean doesn’t allow port 25 do your research correctly

[@FluxxSet]

@@Secclaw for new accounts they have added this rule recently, for older accounts they allow

[@FluxxSet]

@@Secclaw if you gave them valid reason in support portal they may allow

They don't, I already had a long talk with them, they just keep pushing towards their partner sendgrid
