[imp] PGP -(gpg) create keys not working

[Interpost.biz Webmaster]

<p>
        Hello,<br />
        <br />
        I can't seem to get the horde 5 Groupware Webmail edition  
(5.2.17) IMP 6.2.17 - from the debian stretch repos to create pgp keys  
- no matter what settings I use. I have increases the timeout, etc,  
tried the weakest, 1024 keys, etc but I always receive the error  
message  keypair not created, and I cannot find any errors or  
mention of this in the logs, anywhere (syslog, etc).<br />
        <br />
        We are using php7.2 latest on the server, and mcrypt is not  
available - is there any chance that this is the problem?  (we do  
have php7.0-mcrypt installed, however).<br />
        <br />
        We are using /usr/bin/gpg   - are there any  
arguments we need to add to the binary location in horde gnupg or  
imp?</p>

If I create the keypair manually via the command line using gpg then  
horde/imp imports the keys properly and pgp can be used. I need to  
allow the user to create them, however from within their imp  
preferences.

Can you help?

Thanks,  Ed
