Iphone mail not sending and receving

RandomVersion

When i try to send an email using my phone it gives me a error “Cannot send email”.
I used “mobileconfig.php?only_email&app_password” to install the profile.

Note sure if it’s related to your issue but if you know SoGo works in sending/receiving mails, then try changing the account settings in your iPhone for the mail account. I’ve seen similar things on our iPad. I configured the mail account as Exchange (not IMAP) and it seems to work best in that it also syncs other content, like contacts. Try deleting the mail account on your iphone and re-adding it as either Exchange or IMAP (try one or both) and see if that helps.

My config isn’t simple, but when I’ve made back-end server changes, for some reason the Android devices could handle the changes seamlessly (i.e. switched from mailserver1 to mailserver2) but the iOS devices didn’t recover well; they just stopped connecting and gave that “Cannot send email” error and lost all incoming new emails but I still had the cached content. To “fix” things I’d delete the mail account on the Apple device, re-enter the info, then it all seems to come back and refresh/update – at least for a while.

While adding the exchange account it gave a error “Exchange account Unable to verify account information”

Also when opening the mail app i got another error “Cannot get error The connection to the server failed.”

Sounds like one or more ports might be blocked. possibly via firewall. You might also have an issue with your certs, too.

Specifically, I’d check that port 80 and 443 are working for web (which are needed for the Exchange verification piece since it’s in the nginx config) and that ports 143,587,993,465 in addition to port 25 are working for mail (depending on whether you’re using TLS, SSL, etc.). You can google how to do this, but basically you want to make sure mailcow’s docker apps are “listening” and/or responding appropriately to requests on the correct ports. (e.g. is your HTTP_BIND, HTTP_PORT, HTTPS_BIND, HTTPS_PORT config in your mailcow.conf file going to the right ports on the right hosts?)

Note that some ISPs <block> certain ports, especially port 25. There are work-arounds but port validation is the first place I’d check.

Does mail work for other devices, or is it just the iPhone having issues? I’d also do some checks to compare on-LAN vs access from over the WAN/internet.

Another thing to check – and this could be a stretch – are your DNS settings on your mailcow host working (i.e. can you do successful DNS lookups?) When my DNS got messed up, I saw really weird behaviours with mailcow that took me a while to troubleshoot before I found out it was the DNS.
