Should sending email via sendmail result in a long wait?
In my previous hosting setup I used the
sendmail command to send email when I needed to notify myself about system occurrences.
But I've been trying it out in DigitalOcean, and it consistently takes almost exactly 1 minute to execute.
Is this expected? Maybe an intentional rate-limiting measure? That would be fine, but it causes certain actions on my site to time out. I could execute the command in the background, but I'd like the exit status to tell the user if there was a problem (e.g. if they're using a "contact admin" form).
So: what's going on, and is there a way to mitigate it?
