The setting is:

 

G_SPAM_ALIAS_ANY "+"

 

(only valid if no existing email addresses contain a plus, otherwise maybe use ++)

 

I would hesitate to enable it but it depends on your users a bit.  It gives every user an infinite number of aliases which may bite you or them one day :-)

Does SurgeMail support subaddressing using "+" in the local part of the inbound recipient address as suggested in RFC5233? I. e., is it possible to have email for

joe+urgent@example.com

joe+somewebsite@example.com

be delivered into the

joe@example.com

inbox, where it can be filtered by server- or client-side rules? This is a popular feature supported by Gmail, FastMail, Outlook.com and many others, and is useful for managing email from spammy senders.

It doesn’t work out of the box, but perhaps there is a setting to enable it? If not, please consider adding this feature.

Best,

Chris
