Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no
My ISP blocks outgoing port 25, and I can’t find a free SMTP relay service for the life of me, they all want my credit card or want me to wait an obscenely long amount of time to have the possibility of being approved. I was wondering if instead of outgoing port 25, if I could use 587, and still use port 25 for incoming E-Mails, as receiving emails works fine. I just can’t send any. Thanks for the help in advance.
Here are some error messages
The SMTP mail server cannot send emails to other servers because outgoing port 25 is blocked in IPv4.
