Current alternatives for SMTP with TLS 1.3

[LeusKapus 1]

Hey all,

 

Wonder if you can recommend a good alternative to Indy to use SMTP with TLS 1.3, since it is not clear if this will be implemented in any foreseable future.

 

I used to use SecureBlackBox but they got acquired and now there is no way to buy it as a separate component without spending $2,000 in a license for a thousand others I don't need (as nice as they may be).

 

Pricing is a critical thing - I'm not getting a dime for the work I'm currently doing, so at most I'm able to spend a few hundreds in a component for this.

 

Looking forward to your recommendations!

With curl. See the examples. You can read how curl is used in this forum post and the follow-up links.

 

With best regards

ICS has various components for SMTP mail, all with the latest SSL/TLS., free from  https://wiki.overbyte.eu/wiki/index.php/ICS_Download

 

Look at the OverbyteIcsMailQuTst sample which can now be downloaded pre-built.

Indy's support for TLS 1.3 has already been implemented here, it just hasn't been merged into the main codebase yet.   There is a difference.  You are free to try the code for yourself and see if it meets your needs.  Eventually, it will get merged in, I just couldn't tell you when.  That doesn't mean you can't use it today.  Other people are.
