Re: Allowing Special Characters in Email addresses

This really feels to me like a “oh crap somebody put this email address on 10,000 pieces of customer correspondence and now we have to support it” problem. It’s about the only excuse I would consider valid. Sent from my iPhone > On Mar 25, 2021, at 19:00, John Levine wrote: > > It appears th

Re: Allowing Special Characters in Email addresses

Hi Wietse, I just got around to testing these parameters this evening. They work as you suggested but I'm concerned about the potential security implications. So I'll do some more research in this area and see whether this is still worth pursuing further. Thanks for your help, Paul On Wed, Mar

Re: Allowing Special Characters in Email addresses

Hi Matus, No we don't need to support UUCP addresses. We just need to allow the usage of special characters in the local part of the email address. With regard to UUCP i've also looked at the parameter swap_bangpath and tested with this enabled. However we don't need to rewrite the bang "!" to "@"

Re: Allowing Special Characters in Email addresses

Hi Jaroslaw, Yes I think your correct. Just some further into, if I add the sender's IP to mynetworks then it will accept the email with a special character "!" in the local part. So it seems postfix can accept special characters, I'm just not sure how to allow this for every sender. Regards, Pa

Allowing Special Characters in Email addresses

Hi, Is it possible allow the use of special characters safely in the local part of a email address. We have a need to be able to accept emails that include special characters like ! e.g. joe!b...@example.com When trying to send a test mail on a test server I get 'Relay Access denied' ``` postfix
