WP Mail SMTP: What do the SSL/TLS options mean?

When setting up the WPForms WP Mail SMTP plugin, I got this choice:

Encryption: ( ) None ( ) SSL ( ) TLS
For most servers TLS is the recommended option. If your SMTP provider offers both SSL and TLS options, we recommend using TLS.

What do those options mean? Do they mean (like in normal conversation):

  • SSL = SSLv3
  • TLS = at least TLS 1.0

or do they mean (like in Outlook and some other mail clients):

  • SSL = TLS
  • TLS = STARTTLS

I was assuming the latter, because that is really common with mail stuff.

But if that is the case, why would the plugin recommend to prefer “TLS” (STARTTLS, which is insecure) to “SSL” (TLS, which is safe)?

Sample complexity of mean estimation using empirical estimator and median-of-means estimator?

Given a random variable $ X$ with unknown mean $ \mu$ and variance $ \sigma^2$ , we want to produce an estimate $ \hat{\mu}$ based on $ n$ i.i.d. samples from $ X$ such that $ \rvert \hat{\mu} – \mu \lvert \leq \epsilon\sigma$ .

Empirical estimator: why are $ O(\epsilon^{-2}\cdot\delta^{-1})$ samples necessary? why are $ \Omega(\epsilon^{-2}\cdot\delta^{-1})$ samples sufficient?

Median-of-means estimator: why are $ O(\epsilon^{-2}\cdot\log\frac{1}{ \delta})$ samples necessary?

Does the ‘Obsession’ condition mean that the character loses their 9-again ability from other sources when not pursuing their obsession?

The condition ‘Obsession’ on page 290 of my book reads as follows.

Something’s on your character’s mind, and she just can’t shake it. If she’s abiding by that obsession, exploring that emotion, or otherwise pursuing the object of the obsession, enjoy the 9-again quality on all rolls. When she’s not, you lose the 9-again quality.

Resolution: Fulfilling the obsession, therapy.

Does the wording of ‘you lose the 9-again quality’ mean that other sources of 9-again, like the two-dot bonus from the Professional Training merit, are no longer applicable until the condition is shed?

What does “immune to poison” mean in Nature’s Ward?

Circle of the Land druids get the Nature’s Ward feature:

When you reach 10th level, you can’t be charmed or frightened by elementals or fey, and you are immune to poison and disease. (PHB 69)

My question is specifically about the “immune to poison” part. Does it make you immune to poison damage? To the poisoned condition? Both?

Treating it as natural english, my hunch would be the last, but is there official clarification?

What does it mean to avert your eyes?

Medusa and Umber Hulk and probably a number of other monsters suggest that a target can avert its eyes to avoid its effects.

For example, the medusa’s Petrifying Gaze:

Unless surprised, a creature can avert its eyes to avoid the saving throw at the start of its turn. If the creature does so, it can’t see the medusa until the start of its next turn, when it can avert its eyes again. If the creature looks at the medusa in the meantime, it must immediately make the save.

I’ve scoured the books but I can’t find what it means mechanically to avert one’s eyes. I’m assuming it’s related to partial blindness or concealment but I’m not sure. So what are all the things that happen when your eyes are averted? Can you cite the rules so that I can understand it as thoroughly as possible?

What does Beacon of Luck mean?

The beacon of luck spell has two effects.

Effect one is a +2 sacred bonus to saves, and effect two is the ability to roll twice for a save (before roll(s) are made).

Once a creature benefits from the beacon of luck in this way, it cannot gain the benefit of this spell for 24 hours.

The spell doesnt say its dismissed when used this way, so its full duration should still be in effect. Does it mean that only the roll effect cant be used multiple times (even with multiple castings) or is even the bonus to saving throws disabled?

What do “magic” and “bearing magic” mean for Detect Magic?

I am wondering what “magic” means within the context of 5th edition D&D, particularly as it relates to the detect magic spell. I am familiar with the “The Weave of Magic” and spells slots and such.

The detect magic spell allows you to sense the presence of “magic” and shows a glow around creatures of objects that “bear magic”. But what does this mean? This same question applies to the dispel magic spell and I suspect other spells.

Lets imagine a scenario in which a spellcaster shoots a magical ray of ice at a tree and freezes it. What is “magic” here? Is the spellcaster magic while casting it? Is the ray magic (but not a creature or object)? Is the frozen tree now magic, even if encased in mundane ice? Once the ice melts is the water magic? And if the tree has residual damage from the spell, is the tree now magic, or its damaged areas?

I’ve been playing detect magic pretty loosely and it has worked fine, but sometimes I’m not sure what to highlight in the world. In these examples for example I would not highlight the defrosted damaged tree or water, but maybe I would highlight “residual signatures of magic” or the like. I would likely also highlight a giant cube of ice created through magic, even if it is not strictly described as magical or even described as part of a spell, but merely a consequence of it. Would starting a forest fire with produce flame mean the whole forest fire is magical? I suspect not, but I could be convinced.

I’d like some guidance on what draws the line between magical and non-magical.

In the wan oracle curse description what does “inflict spell” mean

From Pathfinder SRD (emphasis mine)

Wan [3PP]

Source Oracle’s Curse, copyright 2014 by RJ Grady, published by Tripod Machine.

You are pale, sickly, and languorous, with one foot in death’s door.

EFFECT

You have the fatigued condition, but are immune to the exhausted condition.

At 5th level, you learn the “inflict” spell of any level spell you can cast.

At 10th level, add ray of exhaustion to your spells known.

At 15th level, add waves of exhaustion to your spells known.

I was skimming through the oracle curses list on pathfinder srd and found the curse quoted above. I’m confused by the wording is there a spell called inflict I’m not aware of or is it a method of delivery. Maybe it’s referring to inflict light wounds and inflict moderate wounds. That’s my best guess but I’m likely wrong on that.
