Re: [Patch] Use str_replace instead of preg_replace in Net_SMTP/SMTP.php

Quoting Matthias Pigulla <mp@webfactory.de>:

this patch will substitute two preg_replaces in SMTP.php with str_replace. That's not a big change; however, as all data sent passes through these calls, it makes a performance difference - at least for me ;)

I've committed the comma-doubling change - thanks. However, I need someone to indulge my lack of testing time at the moment and convince me that the first change really does what it's supposed to do and won't miss things/double newlines/etc. Thanks, -chuck -- "But she goes not abroad in search of monsters to destroy." - John Quincy Adams
