Topic: iRedMail Pro defaults to smtp port 25 . Not able to send mail.

We have not been able to successfully get the iRedpro working. We used iRedmail Eassy to install and provide the pro license key. The mails are getting blocked due to it trying to send on port 25. My understanding was that by default this would be 587 and not port 25.  Softlayer does not allow port 25 and we do not want to open it either.

How to configure the default to be port 587 only for sending email and NOT to port 25. All files say do not edit, managed by ansible .
Here are the lines from mail.log that indicate the connection going out to gmail at port 25.

Re: iRedMail Pro defaults to smtp port 25 . Not able to send mail.

Reinstalled using the iredmail easy. I thought the default was not to use 25. It still has the same issue. All outgoing mail seem to default to port 25.

Scratching my head......

Re: iRedMail Pro defaults to smtp port 25 . Not able to send mail.

Port 25 is used for communication between mail servers, it MUST be open and it's the only one port used to connect to other servers.

You need to contact your network ISP to open this port.

Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?
