Been using Centos and Squirrelmail since early in Centos 6 cycle. IIRC, I used to be able to attach more than 4 pictures to an email. Now I can't, four seems to be the limit. Picture file size doesn't seem to matter, they can be 50k or 5 meg each. I upped the limits in php.ini for the following parameters to see if this would have any bearing on the issue:
post_max_size = 20M upload_max_filesize = 15M
The way I see this is that I should be able to attach [more than] four pics of say, size 100K, to an email. I can't. Within Squirrelmail I go to 'Compose', put in a recipient, subject title, and in the body of text lets just say I add "test case" (as an example). Then I go to 'browse', select a [pic] file, click 'add' (which attaches the pic to the email), and repeat this for a total of four files. When I try to attach the fifth pic, the 'email' frame goes blank, nothing shown. To recover the text I can select 'Compose' again and squirrelamil will state I have an email in 'draft' and do I want to open it. If I click 'ok' I get my email back minus all attached pics. Cycle repeats itself if I try to attach pic #5.
I've googled the web looking to see if others have had this issue, and a buddy helped me a bit, but nothing definite shown to resolve. I've got to figure its a PHP issue. I'm currently patched to Centos 6.9.
Any help appreciated as to what to look for...
