RE: [Phpgroupware-developers] Sending email with attachments

[Don Graver (dgraver)]

I do not use the email app, but I am quite certain it is not the mail
server I use, since I can use other email clients and send very large
files.  I am not using apache2, so I don't think that is the problem.
Since I am able to get the larger attachments sent when changing the
php.ini memory and max timeout...it leads me to believe that it is phpgw
and not my server.  

Just for debugging purposes, I noticed that when sending the 1MB file it
went through the 'do' loop 17,151 times!!!  I'm pretty sure that is why
things are timing out or using to much memory.  

P.s. just a quick look at the email app, and I see that it does not seem
to use the same 'send' class as the calendar app.

please confirm that you can send larger attachments with the regular
email app

That way we can narrow down whether it's a phpgw issue or your server
config

With apache2 php.conf (not just php.ini) needs to be configured to allow
larger uploads
