build error: conflicting types for 'snprintf' on OS X

[Jiří Navrátil]

so far I used only OpenBSD version

today, I’m trying to compile OpenSMTPD cloned from git on OS X

Darwin Kernel Version 14.4.0: Thu May 28 11:35:04 PDT 2015; 
root:xnu-2782.30.5~1/RELEASE_X86_64 x86_64

instructions from README.md

during make, I ended with

Re: using SPF or DKIM instead of greylisting?

[Jiří Navrátil]

V 30. května 2014 at 11:38:43, Gilles Chehade (gil...@poolp.org) napsáno:
 What is your anti SPAM strategy please? Are available SPF and DKIM 
 configurations examples for OpenSMTPD? 
 
 Thak you for your recommendations. 
 

I only use greylisting and fopr big hosts like gmail and yahoo, I have a 
script that queries their SPF records to whitelist the MX servers that 
they advertise. 


Thank you for quick reply.

That looks as reasonable way for me. Could you share your script, please?

configuration example for SMTP account accessible from iOS (iPhone, iPad)?

[Jiří Navrátil]

Hello,

I need to setup SMTP server accessible from my iOS devices. Could you help me 
with some sample configuration? I will use stable OpenSMTP version on OpenBSD 
5.3.

Thank you.

Best regards,
Jiri
