Horde fails with large attachments

Is you Horde email failing due to file size attachments? Check the php.ini file in horde:

[root@server ~]# grep upload_max_filesize /etc/psa-webmail/horde/horde/php.ini
upload_max_filesize = 5M

Now edit the file:

[root@server ~]# nano /etc/psa-webmail/horde/horde/php.ini
upload_max_filesize = 5M
Change to required value
upload_max_filesize = 128M

Save and exit and restart horde

Now check the php config file - php.ini for max_uploads and max_post
grep max_file_uploads /etc/php.ini
max_file_uploads = 99999
