@gordoooo_z Not really? Worked fine for me for several accounts. The only thing I recently suffered from in KMail was that it was sometimes stopping pulling new messages until akonadi account was restarted, but I think the last time I noticed it was a few weeks ago already so perhaps it got fixed meanwhile.
@gordoooo_z Authentication method is in "Advanced" tab, while password field is in "General" tab.
@dos huh, weird. Maybe I'll give it another go when I'm on my laptop (primary work device where I'm more likely to actually use a desktop email client regularly)
@dos I suspect if I were syncing up a Gmail or Outlooks or whatever, it probably would have done all the work for me without issue. In this case it's a custom domain email with Rackspace, and the interface is a little ambiguous when it comes to outbound authentication (I set it to LOGIN, but doing so did not reveal a password field? I kinda just assumed it would use the same one as the inbound, but in the end, neither worked. I'm sure I could have figured it out, but in this particular case I don't really care about the specific client enough to want to try lol)
