Hey all, hopefully this is the right place to ask this question. I'm relatively new to managing the codebase for a longtime efiction site (we've been around since 2006). We just migrated to a new web host over the weekend and in the process our email notifications all broke. I've managed to get a lot of things fixed with it, but we're still getting an error message about a broken pipe in smtp_includes.php, which had me looking here and in Github. We're running phpmailer 1.73 still, even though we're on eFiction 3.5.2, and I can see that 3.5.5 on Github is running phpmailer 5.2.14. There have been significant changes to the code, including different file names etc. How would I go about upgrading just phpmailer? I'm leery of just pulling down the files and swapping in the new ones. Mail is completely broken on our test site and I still haven't figured out why so a lot of changes have been on the live site, too, which is giving me hives. I don't know a lot of php nor do any of the other admins so we're trying to figure it all out.
