@murgero Afterlogic is hosted on a another server outside of my cloudron mailserver, so i believe that wouldn't work

Mystery solved; The server i was hosting Afterlogic on turns out is just too slow. Checking the logs it would always time out, which is 15 seconds.
I ran Afterlogic on a much faster server and now it sends emails just fine.
Thanks all for your efforts to help me, it was much appreciated.

@girish I am using Afterlogic WebMail Lite 8, and the test you gave me, it successfully connected to it.

Also checked the PreferStarttls flag and it was already set as true

@murgero Wouldn't that connect to nowhere tho?

@murgero Where do i put that?

@murgero I tried 465 with SSL, no luck, 2525 with or without SSL and no luck.
I added 2525 to the cloudron firewall whitelist but that didin't help either.

@nebulon I tried ticking the SSL checkbox but i got the same error, and yes i moved my mail server to mail.domain.com instead of my.domain.com

Also tried running a SMTP test and all seems okay.

Hi, i'm asking for help here as a last resort as i can't figure out what is wrong.
I am hosting Afterlogic on a another server that doesn't have Cloudron installed.
The problem i'm having is that afterlogic cannot connect to my mail server which is hosted from
Cloudron.
Spark on my iPhone can send emails but some other email apps cannot send emails either eg. Outlook.
So i am wondering if my mail settings in Afterlogic are wrong or is there something else im missing?

These are the settings im using in Afterlogic

@d19dotca I get this now
