I have searched these fora for answers but they all seem to be too old, pre-High Sierra, and not applicable.
A few weeks ago, for no reason that I can determine, my outgoing emails from my work iMac, no matter small, take 30 seconds or longer to send. I use the same outgoing server settings on my MacBook at home. I have multiple accounts that all send slowly. Any ideas why this might be happening and/or how to fix it?
iMac, OS X 10.11

"Email VERY slow to send; High Sierra: [...]I called my work ISP to see if there is some sort of bottleneck causing my sent emails to slow down and they said there's no problem of any kind on their side of the router.[...]"

A Few Thoughts:
Well, many are at home at the moment, working out-of-the-house, or playing video games. So Internet usage would be consumed quite a bit, in a municipality/region with a lot of residents. So, the ISP is doing all they can on their part, if it were something on their side.
So, if an Issue On this Mac, Try the Following:
Try clearing your Temporary Internet Files (Cookies & Cache) of Safari. Cookies perform remembrance of certain site-entered data. Whereas Cache keeps a snapshot of the last time you visited a site. Use this Link: Clearing History and Cache - Apple Communities
Then...
Perhaps something is not responding and is therefore getting in the way.
Then...
Start with running a scan for malware, using Malwarebytes for Mac and remove what is found.
Then...
Sometimes changes are made to the system and then settings (i.e. for the microphone) become manipulated, technically. So, reset both on your Mac.
Your work iMac is on a different network, with a different mail server, and different network setup?
Check with the IT folks supporting the work network and/or the work VPN.
Best guess is a DNS error with the work network or work VPN.
Check with the IT folks that support the network or VPN.
If there is no network then it is expected that emails would not go at all. How is it that they are going without a network? Your computer is connected to your ISP's network which is different than your home ISP network. Then once connected to the ISP's network the email traverses many nodes on different networks before reaching its destination. The routing over these networks is different when sending from your shop connected network than when connected to your home ISP's network.
I believe MrHoffman was referring to a LAN because he referred to "IT folks supporting the work network". Naturally, I use a WiFi connection to connect to the Internet. I called my work ISP to see if there is some sort of bottleneck causing my sent emails to slow down and they said there's no problem of any kind on their side of the router. Therefore I assumed the problem has to do with the outgoing email server settings but, as I wrote above, I have the same settings on my home computer and there's no problem. So I posed the question in case someone else had a similar problem that they've solved.
Your email is routed through multiple network nodes when navigating the Internet. The hangup could be anywhere in the path. The delay could be several nodes past your ISPs router. It does not matter what network is being used. Email is not an instantaneous messaging system. It could take a few seconds to route through a node or it may take minutes. I doubt the issue is on your computer and if it is not, there is nothing you can do about the issue except change your Internet connection thereby possibly changing the routing used.
One thing you could try is changing your DNS servers.
Am I misunderstanding your post? It sounds like you've understood my problem to be that my emails take a long time to arrive. It's that they take a long time to send, hanging up in the Outbox for a long time. Once sent, they are received promptly.
You have one laptop which works fine. You have a second computer which does not perform to expectations. You refer to the former as “home” and the latter was “work”. Rather than confusing the issue with detsils that don’t matter here, I’m going to refer to those as “fast” and “slow”.
You have two ISPs here, and that can involve some combination of network links and different email servers.
Since you reference using same server settings, that implies you’re not using the ISP email services. Which means you’re down to troubleshooting the differences in the two network paths, which can include different DNS settings as well as substantial differences in the network paths involved between the ”fast” and the “slow” computers and the mail server provider.
So... what are the details DNS settings, and what are the differences in the two network paths here?
How are these two different ISP networks connected to the “fast” and “slow” computers?
What are the details of the hardware for “fast” and “slow” computers? Does the “slow” one have limitations such as, for instance, a hard disk?
Are there add-on anti-malware or add-on cleaners or add-on VPN clients involved here anywhere?
To be clear, emails go out from my MacBook at home quickly, using the same outgoing settings.
No, I own a shop; there's no network, just the single computer. I am the entire IT staff. No VPN.
My home laptop uses a different ISP but has the same outgoing server settings and has no problem.
It worked!!!! Thanks. You get a big gold star next to your name!!!
Great news, take care my friend. :)
